Here is another draft, this time also providing the module name. I
dropped the code looking in /proc/modules, as three ways to find
firmware seem a bit too much. I added similar code to the
isenkram-cli package to install needed firmware packages into
/target/, and it seem to work well there. :)
This new version is not yet tested in the udeb, but the key parts
worked when I tested on the command line.
