F10 finally mostly working on ThinkPad T400

[Per Bothner]

I finally this weekend got F10 working on my ThinkPad T400 laptop.
(This has the new Centrino 2 chipset and Cantiga graphics.)
Yeah!  I still have Ubuntu on another partition, but I hope I
can mostly use Fedora from now on.

Compiz works, as does wireless.  However, neither suspend
or hibernate works.  One report suggests compiz may be the
reason suspend/hibernate don't work; so I'll experiment some more.

What I did was take the latest preupgrade (from bzr), make and
make install that.  After running preupgrade, I had to boot
in text mode, which finally worked (after some display errors
in text mode) - and surprisingly I ended up with a working X.
