Parts of drivers/char/drm/ is severely broken in 2.6.12-rc1-mm1 - this is
fair enough since it /is/ marked as broken. So, why am I writing this
mail? Well, I /tried/ to build some of the stuff in there, saw it blow up,
then tried to fix it, then gave up trying to fix it, got it into a state
where it's still completely broken and will blow up pretty bad if you try
to use it, but at least it now builds. I have absolutely no idea if any of
the changes I made will be useful to anyone, but I thought I'd at least
submit a patch with the changes I made, and if bits of it are useful, then
good, if not - ohh well..

See further below for some of the warnings and errors I initially got that
prompted my to try and fix it.

Here's a patch with the changes I made - very ugly, very broken, possibly
worse than it was, but perhaps there are some bits that are useful - you
never know. :
