Yes, I though about making the new stuff optionally configurable.

But another option would be to leave the xnintr_irq_handler() as it was
before and to introduce a separate handler for the shared interrupts.
edge-triggeres interrupts already have the distinct handler
(xnintr_edgeirq_handler()).

I guess the additional code in xnintr_attach/detach() and a few (~1 for UP
and ~2 for SMP) KBs of data are not that critical taking into account where
and how they are used, both latency and cache-wise.
