Sorry, that was not a particularly helpful response.
Checkout Documentation/serial-console.txt in your linux source dir for pointers on setting up a 
serial console. Grab the oops with a terminal program on another PC and then feed it into ksymoops 
on your machine to give you/someone else an idea of where the oops occurred in the kernel and what 
may have caused it.

Even better, install the morse-oops patch and take down the complete oops info via the keyboard leds 
flashing it out in morse code! (I'd go the serial console option if I were you!)

Regards,
Brad
