(This is serious) I'm looking at the possibilty of using the powerfail NMI which seems to already have some code for it in /sys/i386/i386/trap.c Basically, with a bunch of capacitors and a monostable we think we can make a very cheap UPS, which gives long enough to get the system to do little more than just fasthalt or somesuch. If anyone can let me know how feasible this would be or if it's already been done (can't find any more ISA UPS cards) then please let me know.
