I got some info back from Maxim on the DS1620. The rev D chips use the dual oscillator design described in the data sheet. The rev E chips are based on a temperature compensated bandgap design.
The high resolution read routine is based upon reading counter values and residuals... it's beginning to look like the newer chips don't do it... I've got more questions to ask Maxim...
