The Mach64GX is unlike other Mach64's in that it doesn't use an internal
ATI DAC but an external IBMRGB dac, and accessing this DAC isn't yet
supported for ppc in X 4.2.0. Hopefully someone will find some time in
the future to get this working. I suggest you use the "fbdev" driver
instead if you want to use 4.2.0, or use Xpmac if you want acceleration.
