Tested it myself. what works:
- minidp ports, active and passive adapters
- hdmi port
- upper dvi port
what doesnt work:
- second dvi port
- dvi->vga adapter on upper dvi port, for vga displays you will need active mdp->vga
- dl-dvi on upper dvi port, dl-dvi should work via apple’s minidp->dl-dvi adapter tho, the adapter was tested to work, dl-dvi wasn’t
To install it you need this ATY_Init and ati drivers from 10.6.7 update for newest imacs.
MacPro users – this will not work, for macpro bios of 6870 need to be embeded into Info.plist of aty_init.
To use with Lion, install framebuffer (atiframebuffer, atisupport, ati6000controller kexts) from that imac update.
