This patch does what I intended to do, but the defaults doesn't change
anything from default setup of the kernel distribution (2.1.65). That is:
If you don't change any of the IRQs during config, it shouldn't
change/break anything.
I still think the patch is a bad idea. We should be moving towards more
run-time configuration, not less. The right way to set IRQ's is with
the setserial command, not by compile-time configuration.
