Don't run sensors-detect on thinkpads, all you will find *IF* you are very
lucky, is the clock generator (*never* mess with it) and the SPD eeproms in
the RAM modules (dmidecode will tell you all about your RAM in a thinkpad,
anyway).

All of a recent thinkpad's sensors are not reachable by the main CPU.  Use
the ibm-acpi/thinkpad-acpi and tp_smapi drivers to talk to them.  And if you
did not do it yet, go to http://thinkwiki.org to learn about your thinkpad
and its drivers.  There is not much on the T61 in there yet, so feel free to
help improve it.

Thinkpad-acpi will export the sensors through the hwmon layer in 2.6.23,
btw.  I'd imagine lm-sensors userspace will be able to talk to it, then.

Just don't do sensors-detect on a thinkpad. It is useless, although AFAIK it
won't touch the broken vital-product-data eeprom that bricked thinkpads
anymore.
