ADC6 and ADC7 on the Atmega8 in TQFP package

As far as I can tell from the data sheet, ADC6 and ADC7 on the Atmega8 are configured only as ADC inputs. They don't appear to be mapped to any of the ports. Is that true?

True! And furthermore, they are only available on the surface-mount versions of the chip.

Thanks! They are working just fine as analog inputs and they need to stay analog inputs on the board I am hacking. I just wanted to make sure I was reading the data sheet correctly.
