I have some information that I've found via hsensor: The T42 has a PC87591 Sensors chip http://www.national.com/pf/PC/PC87591E.html Like members of National's SuperI/O family, the PC87591x is PC01 and ACPI compliant. Intel SMBus? and Philips I2C? compatible I also found this: http://www.notebook1.ru/mb/ibm_t40xx.gif I believe T42s also have a (blacklisted) Atmel EEPROM :( Can someone confirm this? Shawn.
