Ah, I see. Hmmm, which file is the part where it decides to do that? I did
a quick grep, but I didn't find anything useful, unless batten_down_hatches()
is the correct routine.

Hmmm, and then it would do the same thing either way since STOP is part
of the SysRQ sequence on SPARC, right? Well, I think that's simple enough
that even I could do it, if I find the part where it decides to drop to the
BIOS monitor. Speaking of the password entry method - That sort of bothers
me. Doesn't having to hold the sysrq combo while typeing the password
seem sort of kludgy? I should probably figure out how to fix that.
