Hmmm. This reminds me. When I wanted to add a network card, I needed
to find a free IRQ. I checked /proc/interrupts to see what was being
used, but it didn't report all the currently used IRQs. Specifically,
it missed out a serial port, parallel port, floppy controller and
possibly a few others. I had to resort to MSD to find out what I was
using where (and I don't entirely trust MSD anyway).

So, is there a reason why this information is incomplete (as at 2.0.27
on x86 -- I haven't checked since then)?
