Like "ps ax" will give you the ID number, and then "kill -9 xxxx" (xxxx is ID number) ? If yes, you may put that in the waking part of the script, and it will kill the bastard. If that isnt the case, I wouldnt know what to do. I have 2.6.9 kernel, and that might be the case. 2.6.9 works like a charm. Also try to kill as many running apps as you can prior to suspend, just to test, and then resume, and see if it works. ALso try to suspend from console (no X session, session manager running). If it works, you can enable processes one by one, and see which one causes the system to freak, and eliminate the process. I see you use cpuspeed. How about stopping that before suspend? Just a blind guess though. This is what I would try if it was mine. Also just a sidenote, powernowd is a superb CPU speed scaling (on demand) app. You may check that out. All info should be on my site. If you have anything you may add to the site, let me know, and I will post it there.
