asterisk users - Jan 2004 - T100P positional on PCI bus?

I'm about to install a second T100P card in my asterisk system, and now 
I'm wondering how the system determines span-1 vs span-2.  Does the 
position on the PCI bus determine this?

TIA
Mike

A little kernel magic. It is consistent though and after you know what
your looking at, it will be the same until the cards are moved around
again.

Care to explain how they are ordered and how to predict it?

From a hardware standpoint, each PCI slot is numbered.  The chipset of each
system board determines what the order is.  For example, you have a T100P in
what the system knows as PCI4 and no other T100P's in the system the
software will see this as the first T100P device.  But if you add another card
to PCI3, the software will then see it as the first T100P and the one in PCI4 as
the second.  There is no hardfast rule across all systems to determine which PCI
slots are numbered first.  I know the hardware part of that is right.  And
I'm fairly sure the software part is right.  Anyone else?!
