None of the other quirk messages are.  On the other hand, they don't 
affect the behavior as much as this quirk does.

Still, if we do produce a message about it, I don't feel it is
necessary to try and explain the whole situation.  Something as simple
as "Buggy wakeup support, disabling" should be enough for an end-user
who wants to know why typing on the USB keyboard doesn't wake up a
suspended system.
