I don't have a special link to Tyan but I can try.  What information do
you need?

[Strange, the lm_sensors package in F9 doesn't have i2cdetect anymore.
Anything replacing it?]

I see two busses:

  Installed I2C busses:
    i2c-0       smbus           SMBus nForce2 adapter at a000
    i2c-1       smbus           SMBus nForce2 adapter at a040

Using -a to get all the info on those busses I see this:
