That's the way I'm leaning, too.

Not really, unless there's a way to tie properties to a specific 
*instance* of the driver.

The properties are a fallback in case the checksum fails. This allows 
for the scenario where you have one (EEPROM-less) wm chip integrated 
into the motherboard, and a PCI add-on card also with a wm chip on it.
