Bug#627976: display freezing in fullscreen applications in linux-2.6.39

[Tarek Soliman <tarek-spam@zeusmail.bounceme.net>]

Package: xserver-xorg-video-intel
Version: 2:2.15.0-3
Followup-For: Bug #627976

According to an article[1] I tried using semaphores=1 and it seems to
have significantly reduced the freezing. I will test this workaround
some more.
