cannot get rid of arc4 module

[tkalfaoglu]

In an attempt to use my USB TPLINK WN321G (Atheros AR8152) wireless adaptor to create a wifi AP, I quickly discovered that the fedora-15 supplied driver, arc4 has no "Master" mode that would allow me to do this.

So, I tried echo blacklist arc4 > /etc/modprobe.d/blacklist-arc4.conf
and a dracut -f /boot/initramfs-$(uname -r).img $(uname -r)
I even added rdblacklist=arc4 to the end of my kernel line in /boot/grub/menu.lst

I downloaded and compiled madwifi and did make install.

Despite all these, and numerous reboots, when I plug in the wifi adaptor, arc4 still gets loaded..
I cannot even unload it, as it says "module arc4 is in use"

Any ideas what else to try?
