Yikes - I never realized that, but then I never really thought about it,
either.  Wouldn't that also mean that a lot of issues become dependent
on how many slots there are and how many slots are populated, etc?  In
other words, plugging more cards in might make a system flakier - or
more stable, same for moving a card from one slot to another.  (And
that's not just moving it to another IRQ.)

(In a past life, I was a Rambus licensee, speaking of signal
propagation.  I specifically did voltage reference and regulation,
temperature sensor, and CAD tools.  But I was aware of the rest of the
design, and particularly marveled at the I/O and DLL designs.  Now that
I write it, the I/O and DLL simply ARE the crux of Rambus, along with a
protocol to make it all work together, and a few bits and pieces.  The
array was our design that we were bolting on.)
