Just got passive minidp-dvi adapter, and test 5870 eyefinity.
Every port works (all 6) with single display configuration, can’t test multi display due to just one adapter.
No injector needed for hackint0sh. For MacPro you don’t need second card with efi, just plug the card and boot macpro, no output until os booted, but then it works. (Thanks to The Rominator for tests).
2 Gb of Ram is perfectly detected and working. OpenCL works.
Second news is – you can use Lion’s framebuffer drivers in Snow Leo, just copy ATIFrameBuffer.kext ATISupport.kext and all ATIXXXXController.kext from Lion to Snow and Enjoy.
Don’t forget to disable any injector, if your ATI card works in Lion without injector.
So, currently 5870 Eyefinity works fine in Lion and SnowLeo.
According to The Rominator’s tests, only passive mdp-dvi works for now, in single link mode (limitation of passive mode), and native DVI ports works of course.
some usefull info from amd site:
Passive dongles use the DisplayPort connection to receive non-DP signaling from the connector and they ‘passively’ adjust the signals to be compliant with the connected monitor. Passive dongles are considered legacy connections, not DisplayPort connections, therefore they do not fulfill the DisplayPort connection requirement mentioned previously and cannot be used to enable 3 or more displays. They do, however, offer an affordable solution to adapt legacy displays to DisplayPort connections.
Active dongles use true DisplayPort signaling to ‘actively’ translate and re-transmit the signals as the required outputs. Because they use the true DisplayPort signaling, they are considered a DisplayPort connection and meet the requirements to enable 3 or more displays.
