So that's a rage64 covered by atyfb ...

I faered you might ask that ...

Add video=atyfb:mclk=xxx to the kernel boot options (IIRC BootX has a text
input box to type the kernel options.

Now what would be sensible things to try for mclk for your card, that I
don't know. The kernel should report the values used (look for the section
in the kernel boot log that is prefixed by atyfb: - my Lombard used to
report the PLL and clock data there). Try setting lower numbers (vary by
10% or so). Various pages on the net used to have hints on this, back
around 2000 or so. Maybe also check the settings used by older kernels;
PLL autodetection was hard to get 100% reliable, or so BenH said. Max.
mclk/xclk should be 63, max. pll should be 135 for your card.

I don't seem to have a backup of my old yaboot.conf, so searching old
mailing list archives might be your best bet.
