That requires you to set up a dumpdev as well as compiling a debugging
kernel. But, yes, kernel.debug corresponds to /boot/kernel/kernel.
As a side note: If you get the panic PC you can do a
gdb -k /sys/i386/KERNELNAME/kernel.debug
dis 0xADDRESS
and get the disassembly and program listing of the address where things
went wrong.
