Are certain kernel modules permanent?
Every time I try to kldunload if_ipw in FreeBSD7 there is a message that a new device has been detected. Then the interface is automatically configured. I would like to unload the wireless module to turn off the radio and save battery power. That is because the sysctl is no longer adjustable.

Emm, if I got you right, you want to turn off the interface? You can just use ifconfig <interface> down.
What do you mean by 'sysctl is no longer adjustable'? |

I didn't realize that the radio control has been moved to ifconfig. Just tested with ifconfig ipw0 down and see that the radio is now 0. In looking at if_ipw, I couldn't find anything like ipwcontrol from the 6.3 version. I was wondering why battery life is so short with FreeBSD and assumed the wireless radio was always on, but it seems not.
