I didn't realise the installer was copying firmware files over.  It
should be installing the relevant packages instead where possible.

Why do you think it's obsolete?  It is useful to have this file present
in the installer.

I don't think it's right to include symlinks in the package that are
supposed to be managed by update-alternatives.  I would rather fix this
up in the postinst script.
