The graphic card is supported by the xf86-video-intel driver package from the extra repository. The Xorg server makes use of this automatically. There's no need for a Xorg configuration file.

pacman -S xf86-video-intel


Heat issues

According to a forum post you should set some power saving options in /etc/modprobe.d/modprobe.conf or add them to your kernel line in your menu.lst. We use rc6=7 for deepest sleep mode.

options i915 modeset=1
options i915 i915_enable_rc6=7
options i915 i915_enable_fbc=1 
options i915 lvds_downclock=1

As well you could suffer of Kernel Power Regressions.
