I guess it's because Branden doesn't build the powerpc debs himself or Ani's
patches didn't apply cleanly anymore.

I think you need to add a second video=aty128fb and/or video=map:000001 or
similar. Oh, and while we're at it, maybe you also need the libfbdevhw.a from
http://n.ethz.ch/student/daenzerm/download/X4-fbdev-test.tar.bz2 for the
second head to work with fbdev.

AFAIK it may be a problem with 2.2 kernels (for aty128fb) though.

That might be a good idea at any rate.
