I think I've might be experiencing the same bug: soon after resume  (<30
seconds) the display freezes with the symptoms as described above.

Two additional observations:
1.) It is still possible to switch virtual terminals. (This is a real difference to the other sporadic freezes I experience rarely under heavy load) Switching to a text console and back into the X screen restores everything and I can continue to work! Screen input definitely gets through while the screen is frozen. The screen will freeze again some seconds later. Switching VTs helps again. This continues several times (about 5-10 times). After that no freezes any more.
2.) I almost never get freezes when I turn of LVDS and use an external VGA monitor. If I'm not fast enough there will be at most one freeze, which can resolved by switching VTs but then no freezes anymore.

If you are affected as well by these freezes, could you please test if
my observations hold with you as well and report! I guess this could
help to distinguish between different types of freezes and perhaps even
help identifying the problem.

I'm using UXA on Jaunty with a kernel from a PPA:
