Adam,

My W700 has the mesa-dri-drivers-experimental installed. No 'additions'
to grub.conf. 'Display Settings' -> 'Hardware' says it's using the nv
driver, not nouveau. The nexuiz game, which requires 3D, now runs. It
did not before I installed the mesa-dri-drivers-experimental package.

Exactly what's going on under the covers I haven't a clue. There was a
time when developers didn't try to cloak their work. These days we're
told "Don't worry. Be happy."
