Oops that should be:

svn co https://trillian.chruetertee.ch/svn/ports/branches/xorg-dev

That is a good possibility. I only have a sandybridge intel card to
test. The only issue currently know are the nouveau driver (which needs
mesa 7.4.4 and doesn't work with 7.6.x), and the old intel driver.

If it turns out other drivers don't work with the new setup, obviously
we need to make it so that they will work. Although I'm currently got
half a mind to just drop the nouveau driver.
