No, that it works with a powerbook with an older radeon 9000 doesn't really tell
you anything, it is possible older generation has good quality output and newer
one has not. But yes if that works with OS/X using VGA that rules it out.

Actually, I think I was wrong assuming the non-pcbios values could be
problematic. These are still probed and not defaults, they should work fine.
If you tried with git before 2007-01-03, could you retry? There was a fix for
bogus mode regs initialization, not sure if it would have caused trouble with
vga, and that bug shouldn't have been there with stock xorg 7.1 ati driver, but
you never know...
