Last week the latest security patch and Safari patch came out. I was busy at the time so I waited to install them. After I got around to doing it, my late 09 i5 iMac will not get to the login screen. It posts, then the grey screen goes away to the blue screen which thinks for a bit and then kicks it over to the "cosmos" screen (which is fine so far), but after a second or two it goes back to the blue screen, thinks some more, goes to the cosmos, etc.

Things I have tried:
Used the setup disc to verify/repair perms and verify disk (A-ok)
Reset PRAM/NVRAM
Attempted to boot into safe mode (no luck)
Boot into 64bit mode (hey, why not)

I have already reimaged from Time Machine once, and it took 6 hours so I'd like to avoid that again. Does anyone know a solution to get it to boot, or is there a way to roll back updates without going the Time Machine route?
