Are you sure it's not just a bad PIC/APIC config?

Hi all.
I would like to apologise for being a lurker on this list and only popping up when I need help. But I need help………..
I’ve run into an issue that has been stumping my for the last couple of weeks.
I’m developing bios code for a GE CR-11 Compact PCI board.
The chips I’m working with are:
1.06 Mhz Pentium M
E7520 Northbridge
6300ESB Southbridge
I’m initialising the SIU in the Southbridge. I have the port configured. I can see data transmitted and received from and to the serial port using a scope on the serial cable and also on my emulator but I can’t seem to get the receive side to generate an interrupt. Does anyone have experience with serial interrupts on this hardware? Can you run through the steps involved for a very simple rx interrupt config just in case I missed something in the Intel docs. Know of an pitfalls?
