It seems like Android is a bit non-standard in the way it deals with
WiFi, but it shouldn't be a big deal. Most likely, we won't have to
write much code, but the least to do is to provide userspace with the
module name and the proper arguments (for instance the firmware

I think I'll look into it in the end. That's far from being my top
priority at the moment.

Yep, that's the Android interface wonders :)
