Hi Daniel,
  Thanks for the reply.  The patch is already included in the upstream
bug at fdo and Dave Airlie has queued it for Linus.

However it would be nice to get it into the Maverick alpha/beta
kernels since it's breaking a bunch of 3d apps which means it is harder
for people to look for other bugs.

Dave
