So the kernel module is loaded when X starts, but see below.

Something goes wrong when loading the radeon KMS module and attaching to
the hardware.  This means that when X starts it has no way of talking to
the graphics card, and exits.  I hope dumbbell@ (CCd) knows more about
this, since he imported the radeon KMS driver into FreeBSD.
Sorry that I can't be of more help.
Regards!
