Johan: a search turned up the following:

Yayger says:

"Remove the card.
Boot the machine.
Place Card back in.
Boot Machine.

I use this process when my video card and network card decide to share an IRQ after 
an install. This changes the IRQ and everything works beautifully."

Blue 87FIS says:
"shared IRQ's don't cause problems in Win2k or WinXP.

I've had all my PCI cards and my AGP card on IRQ 11 for a couple months and haven't 
seen a single problem, even though my hardware says specifically not to allow that!" 

See the link below (after your text) about IRQ sharing...
