Add synaptics-0.14.6-poll-delay.patch from SuSEsuse-patches

syndaemon is a program that monitors keyboard activity and disables the
touchpad when the keyboard is being used. Syndaemon is commonly used on laptop
computers. Monitored with PowerTOP
(http://www.lesswatts.org/projects/powertop/), syndaemon causing 45 wakeups a
second because of a hardcoded 20 ms timer. This behavior significantly reduce
battery life. This patch introduces a commandline switch to modify the poll
delay.
Running e.g. "synadmon -m 500" uses a 500 ms timer instead of the hardcoded 20
ms one, makes syndaemon disappear from PowerTOP, while still doing a accurate
job. (bnc #386709)
