[ltp] Incorporating Thinkpad Detection into Lm_sensors

[Mark D. Studebaker]

Our plan is to put the DMI detection in two places -
1) sensors-detect, our userspace detection script;
2) i2c-piix4, our SMBus driver for the Intel PIIX4 (82371AB and 82443MX)
   SMBus master.

#2) is based on our assumption that the AT24RF08 is on the PIIX4's SMBus
   (that's the only way our package could access it) and that
   all the suspect Thinkpads have a 82371AB or a 82443MX chip.
   These are identified by PCI ID 8086:7113 and 8086:719B for the SMBus
(ACPI) device.

I would like to know if these assumptions are valid. All the lspci
output
I've seen has indicated one of these chips, or else no SMBus device at
all.
Do we know of any thinkpads not using an Intel chipset?
