[patch 45/71] x86: Add quirk for Intel DG45ID board to avoid low memory corruption

[Greg KH]

2.6.30-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Alexey Fisher <bug-track@xxxxxxxxxxxxxxxxx>

commit 6aa542a694dc9ea4344a8a590d2628c33d1b9431 upstream.

AMI BIOS with low memory corruption was found on Intel DG45ID
board (Bug 13710). Add this board to the blacklist - in the
(somewhat optimistic) hope of future boards/BIOSes from Intel
not having this bug.
