[PATCH 0/3] [UBUNTU]: [Upstream] i915 ignore ACPI lid status to determine LVDS connection

There have been many quirks to ignore the lid status reported by the
ACPI bios. Further, this list is not know to be complete yet. Due to this
incorrect lid status reported, many laptops get a blank screen without these
quirks. Looking at the long quirk list, upstream has reverted the code which
takes this acpi reported lid status into consideration for i915 display. This
means that the "no connector reported" error will no longer be seen with
the upstream code.

The patches in this thread do the following:
1) revert the quirk for blacklisting an acpi bios
2) adds and uses a macro definition from a patch. This macro definition is
used by the upstream patch which ignores this lid status.
3) cherry picks the upstream patch which ignores the lid status.

Kindly do consired merging these changes in Lucid.
This will fix the bug 515246 on launchpad reported by multiple users.
