In this case /lib/firmware/dvb....fw
But wouldn't it already need to be yum searchable {fedora} for it to work ?

Could that be:
- try other known packaging types eg on Fedora - check suse rpms, debs ?
or
- download the manu's driver {that includes the fw}
- fw cutter or similar to extract fw.
or
- google filetype:fw {don't think that works} search to find a file download
- download it and size, md5sum against known chksum {who would be 
authoritative} ?
     {ie fedora can't/won't carry fw but it is around; want to be sure 
it isn't dodgy}

I guess it is a bit like codeina, but the user didn't create the 'needs 
driver', 'needs firmware', and 'needs app' event, rather the plug event 
created it. Is this PackageKit's place in the scheme of things or should 
some lower level be doing it ?
