I solved the error by ensuring that intel_agp gets loaded before
radeon. This is actually mentioned in the wiki but I didn't notice
it at first. But that didn't make any difference for the X11 results.
I got X11 working by disabling KMS (kernel option 'nomodeset').
Still strange, since the original system worked fine with 'late'
KMS enabled. The only difference (apart from all the updates) is
that I replaced grub-legacy by syslinux.
A world of exhaustive, reliable metadata would be an utopia.
It's also a pipe-dream, founded on self-delusion, nerd hubris
and hysterically inflated market opportunities. (Cory Doctorow)
