Fedora 11 only comes with 1.6.4 right now and the ATI drivers included in 
F12 and Rawhide have major regressions for my 4850 Radeon:

KMS:RV770PRO:HD4850 1G VRAM+onboard nouveau conflict: system freezes on 
login screen

This one can be worked around by using nouveau.modeset=0 on boot but then 
the performance is much worse than it is in Fedora 11:

KMS:RV770PRO:HD4850 1G VRAM performance regression from F11 to Rawhide(F13)

While the slower performance of the UI is bearable the video playback issue 
is more problematic because unless you restrict yourself to low resolution 
youtube videos the playback becomes practically useless.

Is there a possibility to compile the driver that ships with Fedora 11 for 
Fedora 12/Rawhide and boot with nomodeset to get around these regressions 
or is the older driver fundamentally incompatible with the Xorg/DRM/KMS 
versions shipped with F12/Rawhide?
