Because both drivers can actually drive your hardware.  Drivers are
supposed to be _able_ to bind to any hardware they support, which is
100% correct and fine.  Where this starts to break down is that, of
course, only one driver should bind to the card.  So you get to add
orinoco_cs, hermes, and orinoco to your /etc/modprobe.d/blacklist file
(or wherever Arch keeps the modprobe blacklist file).
