With gentoo-sources-2.6.27-r8 and AccelMethod "EXA" you'll get your 3D

I have same issues, and I've filed bugs on freedesktop bugzilla, here they're:

http://bugs.freedesktop.org/show_bug.cgi?id=19873
http://bugs.freedesktop.org/show_bug.cgi?id=19738

So, I think we just have to wait till intel developers fix these issues :)
