this is a VIA P4 PB 400-L, it has a strangely arranged built in sound 
thingy that has three mini-plug ports, which apparently change from 
being line-out, line-in and mic-in to being front l-r, rear l-r and 
center-sub if it detects 6 channel operation.
the VIA bios setup has several menus but it seems like some control i 
really have over irq settings is whether or not irq activity is 
enabled or disabled on the various channels.
theer is one menu that i can shange whether or not each irq channel 
is assigned to [PCI DEVICE] or reserved. i tried reserving 10 and 
then putting an option line in modules.conf for the snd-via82xx
options snd-card-0 irq=10, but it didn't seem to move it..

cat /proc/interrupts shows that my sound card (VIA8233) exists on irq 
5  with (one of three)  usb-uhci, eth0   (!)
