In fact, you must have the lm_sensors modules compiled for your 
hardware. The situation is alot better with linux 2.6 than 2.4 because 
the lm_sensors are right into the kernel tree by now (in the "char 
devices" section I think)
You have to find the good driver for your i2c bus (i2c-isa works in most 
situations, but if there's a better driver, use it) and for your chip 
(maybe one of lm*, but there's no lm77 which must be handled by one of 
the other lm* drivers).

You'll find more information at http://secure.netroedge.com/~lm78/

When you've loaded the good drivers, you should see your sensors in 
/sys/bus/i2c/devices/* (in 2.6) or /proc/something_I_don't_recall/ (if 
you have a 2.4 kernel and i2c-proc loaded).

Bye !
