Apparently single-stage firmware just skips the second step that's used
with two-stage firmware, so instead of looking for 0x5A in that register
we probably just proceed on after Step 7 of section 2.2.1.2 in the 5.1
spec.  Can you give that a try maybe?  We might need to add quirks for
certain cards so we know if they have one or two-stage firmware, though
that may not hold if there is also two-stage firmware for 8381 cards.
