Speaking for TUXEDO, we would like this to be generic as possible. The TUXEDO EC firmware differs in some parts to the Clevo one, but the flashing / updating procedure is the same as with the Clevo firmware. In other words, there is absolutely no need to do any DMI checks since the updating procedure is the same for every Clevo EC.

I like the idea checking for the PCI subsystem vendor/device ID. Let's do this.
