I've been using the `nv' driver for a long while now, but have now need for
XRandR support, so I dediced to try nouveau once again.
I compiled a new kernel from nouveau's git tree (with KMS enabled), a new librm
and a new nouveau driver, all from the latest git trees.

But when I try to start the X server it fails with:

(EE) NOUVEAU(0): [dri] unable to reference front buffer: -12
(EE) NOUVEAU(0): [dri] NVDRIFinishScreenInit failed, disbling DRI
