[PATCH] Make the Xorg smart scheduler smarter

[Erik Andrén]

Hi,
In an effort to reduce power consumption on my laptop, I'm trying out 
different patches to reduce the amount of wakeups on my machine and 
tracing the process using the powertop utility.
One of the biggest offenders for my laptop is the do_setitimer function 
in Xorg. Arjan van de Ven has developed a patch which optimises the 
smart scheduler and works around this problem. [1]
I have been using this patch now for a couple of days without noticing 
any problems and it has reduced the amount of ticks per second immensly.

Please review and consider for inclusion in Ubuntu Hardy.

With kind regards,
Erik Andrén
