Fixing up the interaction between the gtt driver in intel-agp and the i915
drm modules is my current pet project. We can't remove the gtt support
without breaking old non-gem userspace code, though. So my idea is to
create a private, direct interface to the gtt for gem and implement the
agp stuff on top of it. First step in this direction is my patch-pile to
seperate the gtt support code from the agp driver I've sent a few days
ago.

Does this sound like a reasonable plan to go forward? Obviously my patches
conflict with all recent patches against intel-agp. I've you'd ack the
general direction I could rebase these patches at a convenient time and
then start with clean-ups and killing duplicate code when you've merged
them.
