Using gdb to debug the kernel is not an easy trick. You will need
a kgdb patch for the kernel, and 2 computers. 1 for running the kernel,
and one for the debuger. These computers should be connected using a
serial (RS232) cable.

Please take notice I haven't done this since the 2.0 days, so things
might have changed, but I don't expect they changed much.
