Technically, you should be able to run two cards in two different type 
slots with no problem. You will double the number of interrupts your 
system has to handle. Also if you have to route modem/fax calls between 
the two spans you may run into trouble since the timing could be 
different. In that case you'll want a timing cable (if the cards support 
it) or one dual-span card.
