When rebooting, pass a request to the PROM for it to skip diagnostics and

memory initialization. This reduces memory test and initialization time
from a "in soviet russia, memory test you" time of over 2 minutes for 1GB
on Origin 200, to a more reasonable 12 seconds (and on a Fuel with 2GB,
time goes down from 6 seconds to under a second).
