As-is, the X.org x86emu doesn't work properly on pretty much all ppc machines. That's why the normal int10 soft-boot path is #if !defined(__powerpc__) already in the driver. It seems like ubuntu applied a patch to X.org ATI driver that causes it to use VBE for EDID in many cases where it wouldn't happen before, thus causing the breakage on machines where VBE won't work properly. I've discussed with some of the X hackers who are working on the X ATI driver and they seem fairly unhappy about this patch in the first place. I think at least, the VBE bit should be made #if !defined(__powerpc__) as well.
