I am doing just that, and it works  fine. In fact I was extremely puzzled that on installation
, the PCI serial port card ( ITe), the on board sound card, and the on board ( PC Chips) ethernet 
were all sharing IRQ11, but no conflicts were reported. In fact the serial port card did not work at first, but on 
disabling the network in the BIOS it did then work. On re-enabling the network, all three co-existed despite the fact that 
apparently none of the IRQs  had changed, and there appeared to be a conflict, although XP didn't think so.

This appears to be pure black magic, and I have given up trying to understand it, and just rejoice!
