Ok, so I took some time debugging the issue, I followed the guidelines on the wiki (https://wiki.ubuntu.com/DebuggingKernelSuspend)

As I'm on a fresh install, the issue only triggered once or twice in a series of 5-6 suspends. I suspended with "sudo sh -c "sync; echo 1 > /sys/power/pm_trace; pm-suspend" creating a trace in dmesg.

I added the dmesg output as an attachment, and you can see two call stacks from fglrx. The last suspend in the trace took about 2 minutes to resume, that would be the most interesting one. Though, it could be that this is a different issue than Joep Jansen (comment #9).

Thanks
