Okay, I missed that during porting and had forgotten that I need to deal 
with this.

Everybody (especially those who had problems with panics), please do a

git pull

in the drm sources, and then

cd bsd-core
make
make install
stop X, unload your drm modules and restart X (or simply reboot).

This should fix the problems.

Thanks for testing!
