I saw identical symptoms with several Compaq AP 500s (deskside P3s,
smp-capable). It looked like a persistent bug in Compaq's OEM bios.
Linux, FreeBSD, and NetBSD all showed the same symptoms.
Won't warm boot, but cycle AC and they're fine.

RH L**ux pulled in some Lilo fixes between 7.0 and 7.1 (or 7.1 -> 7.2?
last RH before grub) which fixed the problems for linux. Having
already looked at lilo once, I never had the stomach to read through
the diffs and figure out what the workaround was.

Weasel, or telnet-aware poweron/off, time?
