Yes, the Recovery HD (Mountain Lion) was the first thing I tried, and it didn't work (mouse and keyboard unresponsive). I did however manage to Repair the disk and permissions using my original OS X DVD (Leopard). That did not solve my problem, however. Just now, I actually managed to get into the Recovery HD, and ran the repairs again. This time it actualy did repair some permissions, but I don't know yet if that solved the problem. I'm just now using DiskWarrior 4 to repair the catalog.

I have a Time Machine backup, which ran about an hour before the original crash. I also use Crashplan to backup to the cloud, but I don't backup the entire disk there, mainly my documents and images.

I have now run DiskWarrior 4 on the iMac and after restarting it does seem to go a bit smoother. Keyboard & mouse seem to respond better at login. I can use the computer somewhat. However, kernel_task is still at 101% processor use, and frequently another app takes up most of the rest -- right now it's Alfred using 91%, before that it was Mail and something called bpd (I think?). I'm now checking System messages for the first time, and it's filled with "sandboxd" denying different file-read-data and the like. I'll see if I can do some Terminal command to see what the kernel is doing later, but now I've got to pick up the kids at daycare!

I'm sure when Linc responds he'll have a "Real" way to fix your problem but the other day I was having a Kernal_Task run away on my MBA and after running every possibility on ONYX it seems resolved.

I took the computer to my local Apple reseller today, and after running the Apple Service Toolkit and resetting the SMC and NVRAM, it works like it used to again. The reset was fortunately free! I'm posting a few links here to possibly help others.
