Right, please correct this on the wiki. :)  For Intel, the Linux drivers are 
maintained in-tree.  The BSD variants are generally ported from there (or the 
mailing list) into their respective trees nowadays.

"make install" from a kernel tree will overwrite the versions in /lib/modules, 
but it's easier to just copy them by hand from drivers/gpu/ to /lib/modules.

Some distros are starting to use the kernel headers rather than the libdrm 
headers now.  I think this makes sense long term; however since the headers 
are slightly out of sync it has caused build problems for some packages.
