Craig Butler confirmed my impression that generally there's no downside
from registering a handler for the power fail interrupt on X1 (or V100
for that matter). So I did what I initially thought would be the best
option if the affected machine(s) indeed run stable despite this issue
and added a loader tunable in r247600. By setting hw.psycho.powerfail to
0 you can noe disable setting up the interrupt handler.
