Okay, just for consistency's sake, I ran:

That gave me an oops. pulling it from dmesg and sticking it into a
file, I ran ksymoops, and here's the output in all it's hairy glory:
--->8--[Cut Here]-->8---
ksymoops 2.4.1 on i686 2.4.19-2.burpr. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.19-2.burpr/ (default)
-m /boot/System.map-2.4.19-2.burpr (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
