Depends on how you get module options into your distribution. On mine,
for example (Kubuntu -- and likely most modern distributions), it's
/etc/modprobe.d/blacklist, and adding a line similar to those already
there. I have a situation like this with my girlfriend's laptop -- she
has a card that apparently is "supported" by the 'acx' driver but only
works with NDISWrapper. With 'acx' blacklisted, everything works fine.
