had already tried that. Doesn't compile:

GENERIC:576: `radeondrmkmsfb* at radeonfbbus?' is orphaned (nothing matching
`radeonfbbus?' found)

Same problem with i915

Would be nice to try to determine why the switch to hires console
happens and how to prevent it, as well as getting i915drmkms working
properly.
