It also sounds like what I'm seeing on my EeePC 901. It only happens after resume, which makes STR a little less than useful; the display will, sooner or later, show a single colour (which is, presumably, the result of a display engine hang, as described in the comment immediately before intel_calculate_wm) and, seemingly, be stuck like that until power-off or reboot.
Whether it *is* the same problem, I couldn't say.
Needless to say, this problem goes away if I disable KMS.

Dumb luck beats sound planning every time. Trust me.
