From 072af02d180c1965f30246ea269d208292ed6f05 Mon Sep 17 00:00:00 2001
From: root <root@greentea.conectiva>
Date: Wed, 1 Jul 2009 14:13:52 -0400
Subject: [PATCH] Add IgnoreHotkeyFlag driver option.
Some BIOSes do not set the hotkey flag correctly. Without this option
set, the driver won't change the mirroring state of LCD and VGA
connections if the BIOS did not set this flag.
