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.
Adding the ID to sensors-detect will let it autoload the i2c-piix4
driver, but given that you had manually loaded it beforehand anyway, it
did not change anything for you.
Please check your logs after loading the i2c-piix4 driver. Did it
complain of anything?
Second, please provide the full output of sensors-detect. There are
many possible reasons why no chips were found on your HT-1000, and this
output should help us sort through them. You may also provide the
output of "i2cdetect 0" (assuming that the HT-1000 is the only i2c
adapter on the system; if not try "i2cdetect -l" first.)

BMC are handled by a different set of drivers which were not yet merged
into Linux 2.6. See http://bmcsensors-26.sourceforge.net/ if you think
this is what you need. I can not help much on this myself.
