Direct Rendering Manager problems

[Andrew Kolchoogin]

Dear colleagues,

     I've recently discovered some oddity with DRM on FreeBSD.

     Maybe it's a FAQ, but it seems to me that both on-demand kernel 
module loading and loading them in /boot/loader.conf is broken on recent 
RELENG_6.

     I've an ATI Radeon Mobility 9700 and self-built RELENG_6. When I 
started X, X.org server reports that no DRI available. Manual looking 
into /dev shows that no /dev/dri directory presents at all. Loading 
radeon.ko in /boot/loader.conf doesn't fix the problem. Also no 
DRM-related lines appears in dmesg output.

     But problem goes away after adding line "device radeondrm" to 
kernel configuration file, rebuilding kernel and rebooting the machine. 
Direct Rendering Manager initialises correctly, and node /dev/dri/card0 
exists.

     Are there any suggestions for additional testing?
