Nothing bad--it's just giving the devices a chance to finish whatever
initialization they might be in the middle of before it probes them.
At least, that's my understanding.  Some devices do need it--most, I
think, would probably be fine without it.

Sure.  The savecore stuff shouldn't give you those errors, though, if
your kernel and userland are in sync.

You mean:

> OLD cs0: 0x82
> OLD cs1: 0x86
> OLD cs2: 0x7 (i = 1)

?  This is debugging stuff from the (mostly disabled) IOP
initialization.  It should be removed when someone gets around
to working on that again.
