Is this happening when you start X after the system has been up for a
bit?  I suspect that what is happening is that memory has become
fragmented and since bus_dma tries to allocate large chunks of
contiguous memory for drm, it has a tendency to fail after the system
has been running for a bit.  This ultimately needs to be fixed in
bus_dma, but that hasn't happened yet.
