The PCI bus should be rather bored with 2Mbps per card. Only one card
should interrupt, but I am not sure whether Sangoma or Digium cards
are clever enough to do that. (In an ideal world they wouldn't
interrupt at all, the driver would poll.)

With PCI-Express every card has dedicated bandwidth.

Now that I agree with. It would probably take serious optimizations to
get everything working. It would be fun to try actually.
