Interrupts through PCI-PCI bridge?

[Alan Simmonds <alans@primary-image.com>]

I am implementing a PCI adapter card design which includes a 
PCI<->PCI bridge to provide a secondary PCI interface to a number of 
on board PCI devices, including a 64 bit processor.

Is there any way of passing interrupts from the on board processor
to the host PCI interface using standard bridge chips?  I am thinking 
of using a DEC bridge chip but this does not support interrupts 
(interrupt pin config register=0).

Any help would be much appreciated.
