I am experiencing this bug as well on my brother's Dell 600m; I'm fairly confident the bug is related to kernel mode setting (KMS) on the ATI card. Following the DebuggingKernelSuspend instructions on the Wiki, I see:
<<<<<
[ 0.537451] PM: Resume from disk failed.
[ 0.537474] registered taskstats version 1
[ 0.537716] Magic number: 0:53:725

>>>>
Looking at main.c, all that code is related to drm (which is related to KMS). I will try disabling modesetting and see if the problem re-occurs.
