Oh, it was just suggested by a (presumably very outdated) RAID article I found. I didn't think it would be a big deal for the reasons you mentioned. Plus it's sharing the interrupt with two USB ports which don't even have the motherboard adapter connected to them.
a) You can possibly disable those unused usb ports, some mobo bios's allow you to somewhat granularly disable groups of ports. b) Try changing the mobo BIOS from "PNP aware OS" enabled to disabled or vice-versa. That changes who sets the IRQ's, OS or BIOS. If your board has that option... Of course, it's still the luck of the draw in either case whether IRQs get shared. My take on it is these days you just don't worry about it anymore.
