Subject: ipaq-sleep 0.9: Unbreak, so to say. * If there's something to
 unbreak... Do following: 1. Support logging. Software without logging is now
 software, but a random wreck. 2. Don't do off-by-one errors. 3. Don't bug on
 system every 2 seconds. Instead, do a select on X connection to catch
 touchscreen events ASAP. This doesn't work for keys though, there's larger
 latency. As for other checks, do them once in 5s. 4. The whole thing must
 die. Soon. * Mark configs propery for ipkg. * Should fix #3540.
