I tested the current Natty kernel (2.6.38-020638rc8-generic) on Maverick (as it solves an unrelated bug for me) and can confirm that this issue is still present in that version, i.e., the suspend stops before being complete (the HDDs have been turned off already, though) and effectively freezes the computer.
If there is anything I can do to help debugging the issue, please let me know.
