keeping the module from being loaded should do it.  i think that
adding a line to /etc/modprobe.d/blacklist.conf that says:
    blacklist libertas
will do.

there's some chance that (i can't remember) that libertas will be loaded
from the initrd, in which case you'll also need to do a 
    modprobe -r libertas_sdio
    modprobe -r libertas_usb (on XO-1)
from somewhere like /etc/rc.local.  i say "like" rc.local, because
that file doesn't exist in recent builds, because modern linux
designers have little respect at all for the great, and useful,
traditions of the past.
