how does this work exactly?  I thought it was not about supplying
power, but about the logic voltage, like with the varying voltages of
AGP <?>x slots.

Isn't a PCI slot, even on a PeeCee, either 5V or 3.3V forever,
depending on how it's wired, and never adaptable to the card inserted?
and necessarily so, since the logic pins of a PCI slot are shared with
other slots and thus other cards on the ``bus'' which, if slots tried
to be dual-voltage, could be cards of the wrong voltage?  so, only
cards can be dual-voltage, not slots?

And a slot signifies which kind it is by whether the keying bar is in
the back (5V) or near the card edge (3.3V)---many cards have two
openings for keying bars, but you'll never see a PCI slot without a
keying bar in either one spot or the other.  I have been assuming this
order of affairs but don't know for sure.
