Hi Derek,

You probably just have to stop the nvidia driver from loading by 
specifying "unset nvidia_load" at the boot prompt and reinstall the nvidia 
driver once the system is booted.

That's what I did at least, and I have had no problems while I've heard 
from other people that didn't disable and rebuilt their nvidia drivers 
that they also got panics on boot.
