The bug is still present with kernel-3.3 final.
Further tests confirm that this is an issue specific to the HD6950 card. I
swapped the card with a Radeon HD3650 (RV635 chipset) for testing while leaving
the rest of the system configuration unchanged, and the problem was no longer
reproducible and hibernating and resuming worked fine.
If I change the power profile back from low to default, sometimes the system
will freeze immediately when hibernating. Maybe some registers still don't get
initialized/updated properly?
