Re: More amd64 drmkms radeon

   A DRMKMS kernel from 15th works as suggested above - switches to
   1280x1024 and is fine after (Xorg panics earlier; with the latest
   build from yesterday it even wedged the machine completely).

   On the other hand yesterday's kernel panics as follows:
   [...]
   drm kern error: radeon_cp: Failed to load firmware "radeon/R300_cp.bin"

Do you still have /usr/libdata/firmware/radeon/R300_cp.bin on the root
file system?

We really ought to have a better story if it's not, but that's my
first guess about the problem.

   panic: kernel diagnostic assertion "ttm->caching_state == tt_cached"
   failed: file "../../../../external/bsd/drm2/dist/drm/ttm/ttm_tt.c",
   line 423

This is a bug in the rat's nest of error branches in the Radeon code,
ugh...
