Kernel modesetting

[tsuraan]

I have a laptop with an intel VGA controller, and I'd like to try the
new kernel modesetting from the 2.6.29 kernel.  What xorg intel driver
version, xorg version, etc do I need to try this out?  Also, will it
be possible to use DRI and Xinerama in this configuration, or is that
impossible for some other reason?
