I think it should be done the other way round (if I understand you
correctly), that is, by adding support for configurations were WAKEUP is
left not connected to the sirf driver instead. I had that use-case in
mind when implementing the driver, and some ideas of how it should be
done, but did not get around to actually implement it yet.
