first of all, to nagaverse, what 10 devices do you run all on one irq?
i have a modem and nic on the same irq and they are fine but that's because they aren't being used at the same time. i have had experience with two devices sharing an irq and there being a problem. but if you don't have any problems then levae it alone. if you do have some obscure problem in the future, then you might want to change some irq's around.
repeat after me, we are all individuals!
