description:
Add glue for a drm2pci module.

This module is not yet ready to exist, because too much of the drm2
code is compile-time-conditional on pci/agp cruft, but it's a start.
With a little work we could factor those compile-time conditionals
into run-time function pointer hooks -- something to do later when we
want drm on pciless devices.
