Keyboard reactive is just normal wakeup event processing. Of course,
we have pretty lousy support for wakeup events in Linux just now. :(
Although I'm glad to say that at least for USB, wakeup events are
basically working, and the main gaps are in platform support (which
unfortunately includes ACPI). It would still be nice to see things
like non-USB keyboards and mice be wakeup event sources though.
And of course, S1 and S3 states working ...

I don't seem to recall seeing the ACPI spec laying down requirements
about displays. Those should be platform-specific. That would be
epecially true of non-ACPI systems, which get to define "standby"
and "STR" states to suit. (And I'd kind of hope the system that Jim
sketched isn't relying on ACPI!)
