I'm confirming this as well. Mine fails at radeon/R200_cp.bin, though.
Loading in rc.conf works alright but the GPU appears to get very hot. I
have no diode on it but it just tries to burn a hole through my laptop.
Again, KMS performance is just as bad as with kernel 2.6.31. I get
better performance without KMS and the system runs a lot cooler in idle
as well. My card is a puny rv250 (aka Radeon Mobile 9000).
