solution for panic at boot
I had the same problem. Every time when my MacBook is forced to reset (due to a crash or lack of power) while Parallels is running Winows from my BootCamp installation, I'm not able to boot my MacBook into OS X, neither from CD/DVD without getting a kernel-panic instantly.
I'm able to boot into Windows though. I tried EVERYTHING before I found this relatively simple solution that works everytime:
Put your Mac into FireWire target-mode (hold apple-T while booting to achieve this) and connect your stuck Mac to another Mac running OS X. Launch Disk-utility, and select the stuck OS X partition. Just perform a repair (you might have to repeat the last few steps when the stuck partition appears grayed out) , let it finish and reboot your stuck mac. Et voila: everything should be back to normal....
I hope Parallels will fix this important issue, but maybe it's up to Apple. It might have something to do with the fact that Parallels unmounts the BootCamp partition in order to use it. Just mounting the disk using the target-mode solution is not enough though, the disk-repair is necessary.
Good luck!
