  But how would the kernel know how to deal with non-identified interrupts?
It has to know how to clear whatever is causing the interrupt on the card,
which means it has to know internal details on each card (i.e. what memory
location to read, or bit to set or clear).  Resetting every card might
be difficult too - how would the kernel know how to reset the card (other
than doing a RESET instructions - at which point you may not have any
fast memory anymore either).
