Yes, that's correct.

Could you try the attached patch, and build with DEBUG=intel?  This should 
dump out the entire EEPROM contents on screen, which would be useful to know.  
(If you have a serial port and a null-modem cable, you can capture the output 
by enabling CONSOLE_SERIAL in config/console.h; otherwise a digital camera is 
probably easiest.)

Thanks,
