No.  Swap is no longer configured at kernel boot time; it is configured as
part of the bootup /etc/rc.  And that initial boot Must work in order to get
the swap configured.

Well, this is more than a corner case.  I have three machines that fit the
lower-end definition above.  (And a lot of the "corner cases" have
real-life backing cases--we're a diverse bunch.  ;)
