Sometimes, there are options to modules, something like
modprobe foo irq=7 io=0x300
modprobe bar irq=5 io=0x600
(but it's easier to list the options in modprobe.conf)
You may be able to find out what options are available (and their syntax)
my checking 'modinfo /lib/modules/`uname -r`/.../{3c574,pcnet}_cs.*', the
kernel source's help, or 3c574_cs.c/pcnet_cs.c
