intel: Compile fixes for base install of SLED11.sp3
Highlights of that distribution include xorg-xserver-1.6.5, kernel 3.0.76 and
gcc-4.3.

This commit results in the tear free option on SNB being disabled, despite
being explicitly set in xorg.conf. Tearing then occurs on some video where it
did not with tear free enabled.

Driver built from previous commit: 97b443f589fb62ba060f09a371be273549f524d0
activates tear free as expected and no tearing occurs.

xorg logs attached for both commits
