commit 12825b220ec4b93c0c00077c5c6f2411a5d869db

Lenovo X60: Native VGA init: Remove the framebuffer offset.

Without that fix, the i915 linux kenrel driver often crash
      when it loads.

That fix puts the framebuffer address at a location different from
      the one used by the i915 linux kenrel driver.

TODO: check if it's really needed.
