I'm in just about the same spot w/ a PCG-GRX570 and S3. I've noticed that with a stripped down kernel, after resuming, I can hit the power button and have it almost completely shut down (although you can't see anything). It does hang, but it seems to get the filesystems unmounted and stuff (they're clean on the reboot). I have Ubuntu linux installed in another partition on the machine, and it does a good deal better resuming (X has some issues, but....). I've tried most of the stuff that I can find via google and the mailing lists. Otherwise, I'm trying to figure out how to proceed (in my spare time). g.
