I was able to solve my IRQ conflict and get my modem, Ethernet, and even my

a different slot. I don't know if it was necessary or not but after moving 
the Ethernet card I booted into Win98 and let Windows "discover" the card and 
reload its drivers. After that was taken care of I booted into Linux and 
enabled eth0, then tried my modem and sound. Both work! Yeah!!!

Seems that this is how things changed:
Device          Old IRQ          New IRQ
Modem          11                  11
Ethernet         11                  09
SoundCard     09                  05
