patch 8b925a3d in mainline.

Recent (i.e. 2005 and later) Sony Vaio laptops have names beginning
with VGN rather than PCG. Update the eeprom driver so that it
recognizes these.

Why this matters: the eeprom driver hides private data from the
EEPROMs it recognizes as Vaio EEPROMs (passwords, serial number...) so
if the driver fails to recognize a Vaio EEPROM as such, the private
data is exposed to the world.
