That appears to be the case.  According to Windows 98 (yes, I triple boot), 
the SB Live! is indeed on IRQ 11.  And according to the complete hardware 
profile I printed out before touching my system, IRQ is used by the following:

- ACPI IRQ Holder for PCI IRQ Steering
- NVIDIA GeForce2 GTS (Gateway - English)
- PCI Modem Enumerator
- ACPI IRQ Holder for PCI IRQ Steering
- Creative SB Live! Value
- ACPI IRQ Holder for PCI IRQ Steering (three times total on IRQ 11 alone!)

So yes, this would appear to be an IRQ conflict.  Is there any way to get 
Linux to recognize this ACPI stuff properly so I don't have to screw around 
with hardware?

If not, the only 100% free IRQ on my system is number 5.  Is it possible to 
reconfigure my hardware to put the SB Live! on IRQ 5?  Will everything then 
be one big happy family, or will that screw up all sorts of other 
settings?  I'm a smeghead when it comes to this stuff, so I don't know if 
there's a reason why IRQ 5 is a no-no or not, or even how to change IRQs 
for a given device.

Any help is greatly appreciated.  I really don't want to have to open the 
case and start poking around in there, but if I know what I'm doing (or at 
least what to do) I can handle it.  Thanks again.  Hopefully I won't have 
to nag the PLUG mailing list too much longer.
