I'm gonna see what happens if I disable the sound card or something to
free up an irq when I get back on Monday.  Do you think manually
configuring IRQs would work?  Thanks for your help.

Here's the output from /proc/pci:

| More Info's about the irq's you will get with cat /proc/pci and
| lspci..
