Whenever I try to enable KMS using these parameters "radeon.modeset=1
video=offb:off video=radeonfb:off radeon.agpmode=-1" My machine freezes.
I have not had this issue with iBook or my PowerBook. However if I turn
off hardware acceleration in Xorg: Option "NoAccel" "False". Then KMS is
enabled but I am in Software Rasterizer. You hardware accleration to
have XVid working or you are forced to X11 for video playback. There any
way to get hardware acceleration working on this video card?
