http://www.freebsd.org/cgi/query-pr.cgi?pr=bin/34030
seems to be a similar problem.
We've seen this with the agp module when it's in the kernel and in
loader.conf. In the agp case, it appears to initialize, but then
doesn't function when other devices (DRM) try to use it. I would guess
it's being initialized twice, too.
