But Matt,

request_irq() is used to register the ISR with an irq#
between 0-12 (for the 440). However, the inbound
message interrupt is hardwire as you stated. How can I
use request_irq() to register hardwire interrupt
signal to the UIC? Or is there another kernel call to
handle such services?

You've lost me, request_irq() isn't limited to Linux interrupt
numbers 0-12 on 440.  Everything on the cascaded UICs has been
populated in the irq_desc and is therefore available.
