Yeah, we don't have that min microcode gunk with the device_id match so we'll have to do something like we did for TSA. I.e., below.

I'll test it tomorrow to make sure it doesn't do any cat incinerations :-P

No worries. Don't know if you want this for any other stable kernels older than that, but it didn't apply there either :)
