I don't believe this is a proper fix, and already said so when reviewing
this code:
http://www.spinics.net/lists/linux-pci/msg46534.html
Short of actually solving the dependencies, it is likely that you will
only move the problem somewhere else.
I suggest you engage will people that are working on a proper solution,
and/or fix the drivers to gracefully defer their probing if their IRQs
are not available.
Thanks,
