I tried shifting the irq around last night, the bios does support this.
I definitely think there's something to this theory, when I put it on
irq 10 the problem got a whole lots worse to the point that the machine
couldn't be used and I had to reboot it (just error messages streaming
past on the console).

Unfortunately, I don't know what else was on irq10 at the time since
they move around when I change the bios settings.

I'm continuing to poke around to find out exactly what's causing
what....
