Subject: [PATCH] x86: add Dell OptiPlex 760 reboot quirk

Hi All,

A bug reporter noted their Dell OptiPlex 760 hangs on reboot unless
reboot=bios is specified.  They have confirmed the following reboot
quirk resolves the issue.  Please consider applying for 2.6.33.

Thanks,
Leann

to reboot through the BIOS.
