OK, I'll just add radeon and any helpers it needs to the initrd and be done
with it.

The situation is as follows:
- in AGP mode radeon needs to be loaded manually before X starts (then uses
r600). Probably tries to do this automatically and fails somehow,
- in PCI mode, X with radeon will be loaded automatically (!) The error
described above (ttm_backend_bind) disables r600 and makes X use radeon+swrast

I have not figured this out yet - what to complain about in a new bug report.
