The Update:
I blacklisted all related drivers, i.e., libertas, libertas_sdio, cfg80211 and ipv6, but still all these driver modules got autoloaded..!!

The method I used: in the file /etc/modprobe.d/blacklist.conf, i added these following lines:
blacklist ipv6
blacklist cfg80211
blacklist libertas
blacklist libertas_sdio

I also tried the same in /lib/modprobe.d/blacklist.conf, but to no avail. Every time the modules were getting autoloaded..!!! 

And also where can I look for this autoload feature..?

Best,

Yes i confirm the loading of modules everytime using lsmod.

I'm using the standard installation of yocto project from Gumstix Repo, and also the PM branch kernel from Kevin Hilman's repo. Kernel version is 3.4. So i did not specify autoloading of modules anywhere.

A grep of module_autoload showed kernel-module-split.bbclass as a reference. Is this the file you are talking about..? It will be good to know if it is because this module_autoload..!!

And moreover I now have a doubt if the blaclisting is not working because of the dependencies. I will reply again after blacklisting all related drivers. Esp. the cfg802 driver.

Thanks Bruce,
