Okay, I can see how I was reading it wrong; I thought the Voltage
Control bit for Vcc was a selector (3.3V or 5V), not a switch of the Vcc
power.  But then there's no status bit for whether the card wants Vpp at
all that I see, and as far as my (admittedly extremely limited)
knowledge of PCMCIA goes, there should be one. In any case, I don't
think the driver is doing the right thing by explicitly turning on Vcc
and turning off Vpp.

Maybe the 0V and NC bits are reversed in the Tadpole docs, and we're
sending "Don't rearrange power?"  I don't have any other pcmcia cards
that I have drivers for, much less ones I am willing to set on fire if
the power is wrong, so I can't test it.
