Lets just say there are still some rough edges and things *I'm* still
figuring out with all this myself. :)

Constructive and friendly back and forth is always appreciated.

Hrm. What does 'ir-keytable' without any args spit back?

If the module has been loaded, then unloaded, then loaded again, it
would move the rc device to rc1 instead of 0. (back-tracking on the
device number can be complicated, for simplicity's sake, devno is
just always incremented when another instance is created).

I know it looks like just a comment, and its ugly, but ir-keytable
actually parses that and uses it to set the active protocol decoder.
That could use some work upstream...

Interestingly, it doesn't seem there's a rule that would actually
load the haupp table in there. Providing a line to add will be easier
after seeing the ir-keytable no-args output though.
