Try the diff to these two, for starters:

--- xf86-video-geode/src/Makefile.am
+++ OpenBSD/xenocara/driver/xf86-video-geode/src/Makefile.am

--- xf86-video-geode/src/geode_msr.c
+++ OpenBSD/xenocara/driver/xf86-video-geode/src/geode_msr.c

There's also some interesting changes to *_driver.c and to lx_exa.c as
well. A worrisome number of #ifdef, rather than
autoconf/automake/libtool magic, but it's still a nice start.

It does help us see how OpenBSD dealt with the lack of V4L2 capability
and with finding the MSR on their platform, among other things. That's
a good start for adding BSD support in general.
