The area where it must interact with power management is wakeup, both remote
wakeup at run time and wakeup from system suspend.  In particular, there's
the question whether or not a device ignoring its input should be regarded
as a wakeup source.

I'd say no.

This raises an interesting question.  Suppose the system gets suspended
while the lid is closed.  At that point, shouldn't wakeup devices be
enabled, even if they were already inhibited?

It's possible that this could be a policy decision, ie, whether
power/wakeup is set to enabled for those devices or not.
However, I'd say that there's only one policy that makes sense in that
case : wakeups should be disabled while suspended.

If we inhibited the device during runtime to prevent stray input
events from being generated, it wouldn't make sense to allow the
device to potentially generate an accidental wakeup while suspended.
