This is quite tangential to the rest of this discussion, but "xx"s in
compatible properties always alarm me if they're the only thing
listed.  It's generally best to give a precise model, then a more
general one: the trade-off is that if you're too precise, it's fairly
easy for the driver to workaround by recognizing and binding to
multiple compatible strings, whereas if you're too general you risk
the driver not being able to determine whether it needs a
model-specific workaround or not.
