Happens here, too... or happened, I think I have a solution. Reseting video card during resume seems like a way to go.
Could you get s2ram.c from www.sf.net/projects/suspend, and add your X31 with same parameters as X32 system, and let me know if it helps?
(You'll need an -mm kernel for parameter to be passed into kernel).
