There was a debate on this a long time ago, and the outcome was that IRQ 0 is invalid, across the kernel, and that it is up to each architecture to carry exceptions (like IRQ 0 for the timer interrupt in x86.) Hinc dictat Linus, so you would have to convince him before any of the arch maintainer could realistically even consider this change.
