I need to test a kernel config change on a remote system. Is there a

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.)
What is this "remote hard-reset functionality", if you don't mind me
asking? Do you mean somebody on the far end of a telephone line?
No, it was a web interface button. It was instant. I assume it either
cut the power to the slice or a controller was hooked up to the reset
connector.
