Subject: [41/74] x86: Add quirk for Intel DG45FC board to avoid low memory corruption

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

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

From: David Härdeman <david@...deman.nu>

commit 7c099ce1575126395f186ecf58b51a60d5c3be7d upstream.

Commit 6aa542a694dc9ea4344a8a590d2628c33d1b9431 added a quirk for the
Intel DG45ID board due to low memory corruption. The Intel DG45FC
shares the same BIOS (and the same bug) as noted in:
