It would have be to be done at the session level, although OLPC only has
a single session and a single user, so the system daemon could connect
to the X server.

http://gitweb.freedesktop.org/?p=xorg/xserver.git;a=commit;h=7e2c935920cafadbd87c351f1a3239932864fb90 is the commit you'll want. It was only added to git 5 weeks ago so it you would want to check for its existance, and get it added to your X server.

The relevant API is X11/extensions/sync.h.  I believe you get the
IDLETIME counter, and then set an alarm for it to go off after five
minutes.  At least that's how I think it works. :)
