Indeed. And the DMI check is bogus too, since the "there can be
delays" is apparently part of the pcie hotplug spec.

So do the sane thing. Retry a few times, with increasingly long delays
(ie something like start with 10ms, then double the delay until you
hit 1s, and then just give up: end result, ~2s total wait, but 10ms
for any sane device that doesn't suck).

No DMI checks, no hacks, not insane default delays.
