I had huge problems with my wireless card...and here is my modprobe.conf

alias eth0 e100
alias eth1 orinoco_pci
alias wifi0 orinoco_pci
options snd cards_limit=8
alias snd-card-0 snd-intel8x0
options snd-intel8x0 index=0
alias snd-card-1 snd-intel8x0m
options snd-intel8x0m index=1

for some reason, after i added the

alias wifi0 orinoco_pci

my wireless worked....I have absolutely no idea why. can someone explain why this happened?? it's really weird..i just don't get it.
