Sorry but this just can't be true. In 2.6.9, hardware monitoring data is
found under /sys/bus/i2c (or more exactly $sysfs/bus/i2c where $sysfs is
your sysfs mount point). If "sensors" work, then /sys/bus/i2c must be
populated. Check again.

Sorry, I can't make any sense of this sentence. Please rephrase.

Do you refer to the fan control features? They should be under
/sys/bus/i2c/devices/0-002e, search for pwm* files.

Looks OK to me. You usually don't even need i2c-dev, it's only used by
sensors-detect and for bus scanning/chip dumping.

+2.6V isn't a usual VCC value, how did you come up with this label?

Wow. Not good. What value does /sys/bus/i2c/devices/0-002e/cpu0_vid
contain?

You're welcome.
