Oh crap, you said "remote system". Somehow I missed that. Ignore my
previous post since obviously accessing Grub on a remote machine would
require a hardware VNC module (if you had that, then you wouldn't have
posted about the issue in the first place, I assume.)
The way I dealt with it, is to use the "boot once" functionality of Grub:

I didn't bother with the panic handler, since I had remote hard-reset
functionality (I recommend it; it can save your day.)
