Level-Triggered Interrupt Advice Seeked.

I was directed to this mailing list for advice on a question I
initially posted on comp.linux.development.system.

Basically, When an interrupt is set by a PCI card I am working
with some memory registers on the card must be manipulated before
the interrupt is ACK'd. From reading past posts and just looking
around I have found that Linux handles things in this order: MASK
irq, ACK irq, run handler, UNMASK irq.

Is there any work-around for this that I can implement with the
2.0.34 kernel?

I need to run the interrupt handler before the interrupt is ACK'd.

Thanks in advance,
Jason Wohlgemuth
