Hi!

I had the same problem about detecting which IRQ the mouse driver uses, and
I came up with the following simple method: Check (from INT table at 0000:0000)
what is the INT 33h handler's segment. Then check which IRQ handler is at
the same segment. This is most likely the IRQ mouse driver uses.

But of course, if INT 33h FUNC 24h is available, one should use it.
