Bug#436076: network-manager: IPW3945 doesn't complete network connection (remains always at 20%)

[Krzysztof Lubański]

I have been experiencing the same behaviour for about 2 weeks now on
Lenny (IPW3945, of course). Compiling and loading ipw3945 module version
1.2.2 patched by Alexander Sack for Ubuntu (look at the site LeTic
pointed out) helps. I'm attaching a diff against vanilla 1.2.2 module
sources.
