Hmm. Perhaps unsupported DAC. You're booting 640x480-60, right? It very
may be that the code was generated in blind faith (read: no hardware
available to test on ).

The last line is your AGP ATI card. It is definitely in the supported list
for the ATI Mach64 frame buffer driver (atyfb).

The chipset has support for some hardware DVD decoding. This is beyond the
scope of fbdev. You may want to check out http://www.linuxvideo.org, but I
doubt they support ATI DVD. From my experience, ATI is very protective of
their DVD/multimedia specs.
The original message has been forwarded to Geert (atyfb maintainer) and the
rest of the fbdev cronies.
