Subject: 2.6.37-rc1-00027-gff8b16d: i915 hang on resume

Screen is hung after some drawing (the fvwm decorations are drawn, but
no other app window contents), after resume from pm-suspend.  The system
had successfully resumed a dozen times since booting two days prior.  I
saw a similar hang with a previous -rc1 kernel (some drawing had
completed).  Running various 2.6.33 - .36 kernels, suspend had been very
reliable.

Xorg.0.log is not interesting; after Alt-SysRq-K it ends in:

(II) intel(0): Printing DDC gathered Modelines:
(II) intel(0): Modeline "1440x900"x0.0   74.08  1440 1464 1480 1600  900 903 909 926 -hsync -vsync (46.3 kHz)
(--) SynPS/2 Synaptics TouchPad: touchpad found

dmesg doesn't have much interesting either:
