Looking at the code it looks like a failure of the kernel side. Is
there a kernel tree that tracks the Linus one with the latest pending
fixes I can try?

I gave a 2.6.27-stable kernel a spin but with poor results (X hung up
after a few seconds). Do the X drivers need rebuilding when the kernel
has been updated?
