Here we go:

root at delorean /usr/src/sys % patch < /home/oliver/freebsd/src/drm-7-stable.20080813.patch
...
root at delorean /usr/src % make -j4 buildkernel KERNCONF=DELOREAN
...
--------------------------------------------------------------
>>> Kernel build for DELOREAN completed on Tue Aug 19 00:12:01 BST 2008
--------------------------------------------------------------
...
root at delorean /usr/src % make installkernel KERNCONF=DELOREAN
...
root at delorean /usr/src % shutdown -r now
...
oliver at delorean ~ % dmesg | grep drm

oliver at delorean ~ % glxinfo | head
name of display: :0.0
display: :0  screen: 0
direct rendering: Yes
server glx vendor string: SGI
server glx version string: 1.2
server glx extensions:
    GLX_ARB_multisample, GLX_EXT_visual_info, GLX_EXT_visual_rating, 
    GLX_EXT_import_context, GLX_EXT_texture_from_pixmap, GLX_OML_swap_method, 
    GLX_SGI_make_current_read, GLX_SGIS_multisample, GLX_SGIX_hyperpipe, 
    GLX_SGIX_swap_barrier, GLX_SGIX_fbconfig, GLX_MESA_copy_sub_buffer

Unfortunately, the machine completely freezes up when
trying a "X -config ..." and the throughput is not very
satisfying as well...

Example:

oliver at delorean ~ % glxgears
727 frames in 5.0 seconds = 145.369 FPS
727 frames in 5.0 seconds = 145.272 FPS
720 frames in 5.0 seconds = 143.927 FPS
...

I'll move that topic to freebsd-x11 tomorrow.  :)
