Not what you asked for, but... perhaps you have a spare FireWire port?
From Documentation/debugging-via-ohci1394.txt:
| There is also a gdb proxy for firewire which allows to use gdb to
| access data which can be referenced from symbols found by gdb in
| vmlinux:
| - ftp://ftp.suse.de/private/bk/firewire/tools/fireproxy-0.33.tar.bz2
|
| The latest version of this gdb proxy (fireproxy-0.34) can communicate
| (not yet stable) with kgdb over an memory-based communication module
| (kgdbom).
