I could probably do some testing here - I have some digi
cards (although only one PCI one AFAIR!!).

I originally added linker_reference_module() because I
wanted to be able to dynamically load a module from
another module, or take a reference to it if it's
already there.  This was a good way to load/unload the
different firmware types after figuring out what the
card type is.

If firmware(9) avoids this necessity, I'm all for doing
away with linker_reference_module().
