I don't want to reboot the server everytime something like that
happens. I'll expect pretty nasty problems will develop after a few
dozen unclean shutdowns like that.

Would ILO work on a server that's unresponsive due to heavy load? The
actual network access isn't a problem so dial up isn't necessary. The
other problem is the server in question probably doesn't have ILO
features on the mainboard.
