after using sleepd for some time with irq= i've had a number of times where irq's would swap on reboot, would it be possible to also allow interrupt labels instead of numbers to catch this?

-- I haven't used the irq= feature myself but from user feedback I've seen on the Arch forums this would indeed be useful.
