pci hotplug, how to unload module ?

[Alexandre <a.hocquel_NOSPAM_@oreka.com>]

Hello,

I've just bought a WiFi cardbus MSI CB54G2, and now that I can setup and 
use it, I have a problem when unplug and plug it again !

I need some setup before using it but after loading module and "uping" link!
Hotplug can load module when I plug it but unlike usb hotplug, pci 
hotplug can't launch some script ! juste modprobe module !
So I add post-install script to modules.conf (throught 
/etc/modutils/network) and now when I plug at first the card it's ok !
Now imagine I unplug it, and plug it again... There is a little problem, 
'cause when I unplugged it, it didn't unload (modprobe -r) module, so it 
doesn't load it again (and so, not launch my post-install script) :(

so is someone knows how to unload module when card is unplug ? or knows 
how hotplug can manage this ?

thanks by advance,

Alexandre
