wicd is being used to start the internet at bootup.
As for any issues(there is, but I think it's more ndiswrapper related).
Attached is dmesg, to give you an idea of whats happening
(I'm seeing the ip command generated twice).

Also there is an issue with using the latest snapshot of gcc
(received an error a few days ago, and Stephen pointed out what
was happening) Which hopefully didn't mess anything up
with libselinux, etc...(you never know, compiled with a bad gcc could generate
wrong avc's)
