Yeah, I see this too on my X300 M22 after the upgrade to external DRM; I
suspect it's once again related to scatter-gather stuff, but I haven't
had the time to look in more detail (certainly before the last changes
to that code in the old DRM, X + DRM on that card failed in other odd
ways, though it would "fix" itself if I restarted X after the initial,
screwed-up session; it would also work just fine w/out DRM).

I think that's because the X server hasn't made it far enough to ask for
the IRQ handler to be installed / enabled... I think it gets wedged pretty
early in the DRM initialization.
