+From 76515c8a369346d76864e55610a6a747d9b152d8 Mon Sep 17 00:00:00 2001
+From: James Simmons <jsimmons@infradead.org>
+Date: Sat, 12 Jan 2013 21:02:12 +0000
+Subject: As the comment suggested in via_outputs.c probing the 3rd i2c bug locks up the P4M900. So we re-enable the via_card_id handling of what outputs to test for to get around this problem.
