(Phil) Added beginning detection for serial EEPROMs. Right now if it

finds anything within 0x50-0x57, it will claim it is an EEPROM with a
confidence of '1' (the least confidence).  Using the PC-100 SPD spec
I should be able to add better detection, at least for serial EEPROMs
on PC-100 SDRAM DIMMs.
