The HT-1000 is (from our simplified point of view) an SMBus master. It
may give you access to I2C/SMBus hardware monitoring chips, but isn't
itself a hardware monitoring chip.

The i2c-piix4 driver found in the lm_sensors is a Linux 2.4 driver, so
it is of no use to you.

OK.  I tried loading the adm1026 module that Martin uses -- no go.

OK.  In any case I am loading the i2c-piix4 modules from the (modified) 
2.6.15 tree.
