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 ...
