You need to use tunelp to get the lp's to use an IRQ. When you do, you can
pick any IRQ you please, though trying to share an IRQ may fail and you
won't get the results you want if you pick the wrong IRQ.

That's not necessary for tunelp. However, it probably ought to default
to using the IRQ you explicitly requested when you insmod (or request
IRQ 0 to poll, just like with tunelp).
