x86: ASUS P4S800 reboot=bios quirk

Browse Source 
Bug reporter noted their system with an ASUS P4S800 motherboard would
hang when rebooting unless reboot=b was specified.  Their dmidecode
didn't contain descriptive System Information for Manufacturer or
Product Name, so I used their Base Board Information to create a
reboot quirk patch.  The bug reporter confirmed this patch resolves
the reboot hang.
