IT8720F chip not recognized by lm-sensors

This may be related to Bug #357766 -- which was fixed in Jaunty.

The problem shows up when running sensors-detect:

Trying family `ITE'... Yes
Found unknown chip with ID 0x8720

In short, it doesn't recognize the chip even though the lm-sensor wiki lists it as supported. I don't know if the cause is the same as for Bug #357766, but perhaps that's a good starting point. I am using a Gigabyte GA-MA790XT-UD4P motherboard.
