Heh, OK. We do seem to get 'down' interrupts though, just not 'up'
interrupts -- so what I have there ought to leave polling on for the Rev
4 modems, while dropping back to interrupts for the older ones where it
actually works.

Or do you think we should base it on the revision rather than the
behaviour -- or just leave the timer running always, even on the older
modems?
