AFAICT the patch is a dummy cp ./src/{freebsd,haiku}_pci.c + sed
"s/freebsd/haiku/Ig" and is missing any integration. Both Makefile.am
and configure.ac.

Since there's no actual users of drm_intel_get_aperture_sizes's
mappable (the code that requires libpciaccess), just return a dummy
value and not bother with any of this ;-)
