Subject: [PATCH 2/2] Update x86emu from X.org

This commit updates the x86emu copy from X.org tarball
(ftp://mirror.csclub.uwaterloo.ca/x.org/current/src/xserver/xorg-server-1.12.2.tar.bz2).

This fixes a compatibility issue between v86d and SeaBIOS VGA BIOS where
the leal instruction is not decoded properly. Read the
http://thread.gmane.org/gmane.comp.emulators.qemu/271806 thread for more
details.

Upstream-Status: Backport
