Subject: [113/145] x86: Add iMac9,1 to pci_reboot_dmi_table

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

----------------
From: Justin P. Mattock <justinmattock@...il.com>

commit 0a832320f1bae6a4169bf683e201378f2437cfc1 upstream.

On the iMac9,1 /sbin/reboot results in a black mangled screen. Adding
this DMI entry gets the machine to reboot cleanly as it should.
