It turns out that a lot of newer systems have 'base peripherals' on
the PCI bus. We presently have no drivers for these devices, so they
are powered down. This is undesirable behavior since it breaks the
system when the base peripherals go away suddenly in the middle of
boot.
# if we ever get generic drivers for memory and/or base peripherals, then
# we can remove the tests here.
