Subject: [PATCH] Psychovisually-optimized HZ setting (2.6.33.3)

This is based on the research I did with optimizing my machine for  
graphics.
I also wrote the following article:  
http://www.paradoxuncreated.com/articles/Millennium/Millennium.html
It is a bit outdated now, but I will update it with current information.
The value might iterate.

Peace Be With You,
Uwaysi Bin Kareem.

+	 3956 Hz is nearly the highest timer interrupt rate supported in the  
kernel.
+	 Graphics workstations, and OpenGL applications may benefit from this,
+	 since it gives the lowest framerate-jitter. The exact value 3956 is
+	 psychovisually-optimized, meaning that it aims for a level of jitter,
+	 percieved to be natural, and therefore non-nosiy. It is tuned for a
+	 profile of "where the human senses register the most information".
