Hmm, well I can confirm that my chestnut43 has the ADS7846 IC in that location.

I've bought a Chestnut43 board and could not get the touchscreen working:

I've looked at the Board and could not find any ADS7846 on it.

You can see a free Pad in the Picture which is attached. I am right that Gumstix has forgotten
to solder the Chip? Or can it be anywhere else?

I've mailed Gumstix about my Problem and they say:
"Each Chestnut43 board has been tested for touch screen function prior to shipment.
Please use the Gumstix mailing list for technical support. "

I want to be sure that this is really an Hardware issue, before I send it to Gumstix for RMA.
