Suggesting the following:

 :firmware filename [MD5_checksum]

The filename should probably not contain path information because it
may get installed in different locations on different systems.  The
checksum is optional and may be used to verify the file.

Should multiple :firmware entries for a single model be allowed?
IIRC, there are some Windows drivers out there that include different
versions of the firmware file for the same device.

I've had a quick look at sane-desc.  That will need support for extra
fields.  It barfs on anything that's not in the "spec".  Anything else
that might break if I were to supply a patch for epkowa.desc that adds
a :firmware field?

Any opinions on the custom field, a la X-* mail headers?

Hope this helps,
