Suspend to Disk failed, now machine's CPU usage makes machine unusable

On my laptop, I have SUSE 9.3 installed. The laptop is a 850 MHz AMD Duron (Compaq). Linux runs great.

I decided to try the "suspend to disk" feature. The dialog in KDE was showing progress, as the "ram" was being written to disk. It got over half way and hung. I let it sit for a while, thinking it would finally finish, but it didn't. Finally, I ended up having to power the machine off manually (locked up).

Now, the machine boots up fine, but is extremely slow. I have found the CPU usage averages anywhere between 40% and 60% all the time, which obviously isn't normal. As a result, my laptop quickly overheats, and the machine becomes unstable - virtually unusable. Subsequent reboots don't fix the problem.

Making suspend to disk work isn't the issue here... how do I undo the damage done by the suspend to disk feature so my machine works again?

run top to see what is using all the CPU bandwith.
man top
Then kill the process by its PID, example
kill 128
See why the process is running.

The processes aren't unusual. Its the amount of CPU time that they are taking.

I have verified this is a KDE problem. I can run Gnome just fine. KDED hangs around 40% utilization. Kopete now fails to connect (it doesn't even give an error - just sits there).
