There are others on this list that are far more knowledgable then I, but those interrupts that show "0" aren't of any concern with the exception that if an interrupt can be freed up, your system might allow that interrupt to be used by other cards, etc.
If you look back over some of the previous posts on this, you'll see where some discussion has occurred that says the interrupt assignments can vary dramatically by motherboard. In other words, some motherboards apparantly have a specific interrupt hard-wired to specific pci slots, including any internal ethernet adapters.
The above list suggests you have several free interrupts available, so moving the digium card to other slots is _basically_ the only remaining steps available to you.
Since your t1xxp interrupt is showing "0", the issue is probably not related to shared interrupts, but rather some sort of incompatibility at the OS/Card level. Others can comment more on that then I can.
