We have generic I2C support for the 8260 (drivers/i2c/i2c-algo-8260.c)
in our version of the Linux kernel, and drivers for instance for the
MicroSys PM826 ("Miriac") module, too (drivers/i2c/i2c-pm826.c).
See ftp://ftp.denx.de/pub/LinuxPPC/usr/src/linux-2.4.4-2002-01-19.tar.bz2
Reading the LM sensor is then just a minor excercise..
