wpa_supplicant breaks iwl4965 
On my Fujitsu Siemens E8410 lifebook.
This is a 2xCPU x86_64 laptop running Gentoo 2.6.26
Everytime i emerge nm-applet it also installs wpa_supplicant and all subsequent attempts to start the wireless interface fails:
wmaster0: read_interface: Cannot assign requested address
Unmerging both nm-applet and wpa_supplicant fixes it nice and simple.
