As far as I can see, this isn't going to work. The functions that need
access to this information are the driver's map_irq() and set_irq(), and
neither of these callbacks is provided a pointer to the driver-specific
structure where I could store the board irqs.

Can you elaborate on your idea, or point me to existing code that
implements it?
