The fallback thing in grub has never worked for > me. When does that ever work? 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: http://weichong78.blogspot.com/2007/04/grub-test-kernel-once.html I didn't bother with the panic handler, since I had remote hard-reset functionality (I recommend it; it can save your day.)
