All the main details on this are on the freedesktop bugzilla[1]. I can
confirm it's still a problem and I've been tracking the intel-next
tree for testing.

Fundamentally the problem is that X can't allocate any memory when KMS
is enabled on my chipset. Without knowing how memory should be
allocated from the kernel by the X driver I haven't been able to look
into it deeper. I've had some feedback from the intel guys but nothing

As always I stand ready to run tests and/or provide additional
diagnostics if required.
