Does anyone have any information on this Super IO chip? I'm guessing it's similar to the SCH5307-NS, which is supported in the smsc47b397 driver. It reports a device id of 0x79 (SCH5307-NS is 0x81). Dell uses it in recent versions of their Precision 380 workstations. Mailing SMSC for a datasheet resulted in a big fat zero. If anyone can supply me with the datasheet or other information, I'll give adding support a shot.
