That is normal ... You are using atyfb, and it works fine isn't it ? what is the output of fbset -i when you use atyfb ? Also you said you added the identity of your chip to atyfb.c, but the Xserver has to be aware of that also. Atyfb should set a var.accel flag, that is the one the Xserver recognizes. actually i think the following are supported for mach64 chips : FB_ACCEL_ATI_MACH64CT FB_ACCEL_ATI_MACH64VT FB_ACCEL_ATI_MACH64GT i guess you should add a FB_ACCEL_ATI_MACH64LT flag, but this should first be fixed in atyfb, and once that is done, send it to me, and i will update the Xserver accordyingly, or maybe someone else can do it, because my partition were i was keeping X stuff has some kind of problems recently. please do it quickly if you want it to be in X 3.3.4 ...
