Default x86: ASUS P4S800 reboot quirk

Hi,

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. Please consider applying.

Thanks,
Leann Ogasawara
