I created my /etc/modprobe.conf using emacs and adding the single
stanza I needed. I do not know how to create a /etc/modprobe.conf
that would encompass all of the hardware on a machine (i.e. sound,
network adapters). However, I did notice in a previous post that you
had /sbin/generate-modprobe.conf installed. My google search for
information on generate-modprobe.conf was not particularly
enlightening. Perhaps you will have better luck.

Hmmm. . . What do the system logs have to say about the wireless card
and/or NetworkManager (assuming that you have NetworkManager on)? Do
the logs show that a HW killswitch is active? Do the logs show
NetworkManager attempting to bring up wlan0 or eth0? If so, please
post those sections of the logs here.

That I don't know. I have not used them and, thus, have no experience
with akmods. Someone on the rpmfusion list could probably answer that
question.
