As far as I can tell, the main kernel configuration issue is to make sure APIC and IO-APIC support is turned on, if your system supports it.  (All SMP motherboards do, and many single-processor ones do as well.)  This seems to give access to 32 interrupts instead of 16, minimizing interrupt sharing.

Should ACPI be turned off in the kernel?  In the bios I can only set cards to the 1-15 interrupt range, but linux and acpi it seems moves these to the 20's.  I looked last night on the lists and found no true answer to this question.  I have 4 TDM's so interrupts below 15 are few and far between, but I do have enough.
