The "Disable touchpad while typing" option in System->Preferences->Mouse launches syndaemon -i 0.5 -k. Unfortunately syndaemon seems to poll every 200ms even when the system is otherwise idle, waking up the CPU and presumably wasting power.
syndaemon has code to use XRecord to avoid polling, but it appears to be compiled without HAVE_XRECORD, even though Xorg appears to provide that extension (judging from xdpyinfo output). It also requires -R to be passed on the command line, although perhaps it would be a reasonable default?
