Hi,

in any preview SL, i can't enable the radeon 3870.

Either using EFI strings or DSDT. Those methods works well in Leo 10.5.7 (dual dvi, sleep/wake, full resolution, QE/CI ...)

I looked into ATIRadeonx2000 plist file, i've got the right ID in stock plist : 1002:9501

I had to remove ATI*.kext in order to have the GUI.

Does anyone found howto ?

I saw the framebuffers seem to have changed in SL.
