Not really.  We must have broken something in 2.6.26, but there were not too
many suspend-specific patches in there vs .25.

What s2ram options are used?

What hardware is there in the box (chipset, graphics)?

clue.

So here I am. Not directly resume hang but may be related. git kernel from ~2 
days ago.

resume succeeded but dmesg indicated tons of:
