Involved in what sense ?

Basically, you take the Linux sources, drivers/gpu/drm/radeon/* and makes
them compilable, runnable and then bug-free under FreeBSD. In the course
of actions, you add the missed infrastructure bits from drivers/gpu/drm/*.

The most infrastructure parts needed for the KMS are already ported in my
kms git branch. Biggest missed stuff is TTM, but I already promised to do
it if somebody takes care of the radeon.

The line count for radeon driver is ~100KLOC, that is twice as big as Intel
driver. I am optimistic that the porting will take 3-4 months, judging after
the Intel experience. Also, I am more then willing to help, but definitely
won't do it myself.
