opengl 3.0 test there doesnt work yet tho and most of gl3.0 specific functions aren’t present yet, but most of modern gpu’s functionality is now possible to use via extensions.
I hope they’re not going to hold opengl3.0 untill 10.7 
Radeonhd 4670 in Imacs is mobility card, its clock speed is 680 for core, 790 (1580) for memory.
Desktop’s 4670 card have 750/800, core clock of desktop 4650 – 600.
So performance should be between desktop’s 4650 and 4670.
Here is table with clocks in all states for this card.
Btw, framebuffer is Shrike;)
There is good news for owners of macbooks with intel graphics and 64-bit efi, who was successfull to enable 64-bit.
10.6.2 beta has 64-bit drivers for all intel igp’s used in macs.
Apple released osx update 10.6.1, it brings no new kernel.
Updating is easy, just hit install button in software update.
The update updates graphics drivers, so hd4850 users need to add their device-id to ATI4800Controller.kext before rebooting, its better to use update dmg for those users.
hd4890 Users – wait for patch for qe/ci
And about leopard security update, it has no new kernel or kexts, so should be safe to install
Amit Singh recently made a post about patching boot.efi for 64-bit support on macbooks(with 64-bit efi).
Here is simplified version of his post:
To run 64-bit kernel on any mac with 64-bit efi you need patched boot.efi file
You can find file named boot64.efi here
It enables 64-bit kernel support for some macmini/macbook/imac/macbookair models, which has 64-bit efi bootrom.
Download file to desktop, open terminal.app and run these commands
cd ~/Desktop
sudo cp boot64.efi /System/Library/CoreServices/
cd /System/Library/CoreServices/
sudo chown root:wheel boot64.efi
sudo chflags uchg boot64.efi
sudo bless −−folder /System/Library/CoreServices/ \
−−file /System/Library/CoreServices/boot64.efi
Commands starting with sudo will ask you for your password.
Next step – add arch=x86_64 to file /Library/Preferences/SystemConfiguration/com.apple.Boot.plist to Kernels Flags section
For example:
<key>Kernel Flags</key>
<string>arch=x86_64</string>
Now reboot, your mac should boot 64-bit kernel, but some models missing 64-bit intel video drivers, for example macbook4,1 with gmax3100, so only internal display will work, without qe/ci/opengl.
if something goes wrong, boot leopard/snowleopard dvd (or another installed osx system) and run this command in terminal
sudo bless –folder /Volumes/YOUVOLUMENAME/System/Library/CoreServices \
–file /Volumes/YOUVOLUMENAME/System/Library/CoreServices/boot.efi
p.s. if you have 32-bit efi, this commands will make no effect for you at all.
Apple released some sources of SnowLeopard 1OSX 10.6
No XNU(kernel) sources this time.
Cmon Apple, dont play like in Tiger times, releasing kernel sources will not increase hackintoshes amount anyway.
At least there is sources of some kexts, for those who needs some kexts with fixes.
How to update:
install Disabler.kext
install this dsmos.kext ( a bit updated to be present in mkext)
reboot
create backup of Extensions folder. just in case:
sudo cp -rf /System/Library/Extensions /System/Library/Extensions_old
update !
good luck
if smth wrong with your drivers after update – u have a backup 
some info:
for radeon hd 48×0 users, binary of Motmot wasnt updated, so if u used patched framebuffers, should work fine still.
for radeonhd 4870×2 4890 4830 users – you will loose qe/ci/3d after update, wait for proper patch.
dont remove AppleIntelCPUPM.kext until install finished, or it will stop with error.
After update done, and you have rebooted twice, remove Disabler.kext and AppleIntelCPUPowe….kext
Dsmos arent working anymore(and its not easy to fix it)
so, you will need decrypted files and install them manualy (until somebody will make installer), dont forget to correct persmissions on files after installing it.
You can find files in irc.osx86.hu #snowleopard, topic, link named decrypts.
I just succesfully created efi rom for 4890.
efi part based on patched 4870 efi rom.
bios part is from msi 4890
since most 4890 based on original amd design, the rom should work with most 4890
edit clocks to the one u have(by default its 880mhz for core) with “Radeon bios editor”
enjoy
you can make a donation too here
The rom image – link to rom image
You can use this flashing instruction – http://netkas.org/?p=90 .
p.s. rom for 4870×2 is coming soon (for working 1 core)
p.s.s. you will still need patched ATIRadeonX2000.kext from irc to get qe/ci, since apple doenst suport 4890.
Smells like a marketing bullshit, because it works, with stock mms/sms app
