I have come across things like this before, but it's generally not an issue if
you simply disable the onboard stuff that you don't need and select the PCI
slot(s) wisely.
I had the situation where my mobo allocated fixed IRQs to each slot, and shared
IRQs between some of them (I can't remember the exact IRQs, but for arguments
sake; 10, 11, 3, 5, 10, 11 in slot order - 6 slots, 2 sharing IRQs.)
In most cases, IRQ 5 will be unused by anything on the mobo, giving one "fixed,
unused" interrupt. This is where I placed my zaptel card.
By disabling my COM ports, I was able to free IRQ3. You can also disable stuff
like USB, Parallel, Audio, secondary IDE, etc. etc, which can all free-up IRQs.

FYI:
We're trying to standardise on a tier one motherboard for the Asterisk
boxes we build for customers and thought we'd try to use a low-end Intel
Desktop Board since even a low-end Celeron has more than enough
horsepower to handle a typical 8x32 PBX.
To make a long story short, according to Intel Dealer Technical Support
(we became Intel dealers in order to get answers to our questions) there
is no Intel motherboard that permits the IRQs to be configured uniquely.
They are all hardwired and shared. This information applies to both the
Intel Desktop Board and Server Board product lines.
Please let me know if your experience differs from what I've been told
by Intel.
Otherwise, you've been warned -- Intel mobos appear to be unsuitable for
use with Digium hardware.
