Ah, good. That's what I was wondering as I was reading your and his/her posts. Were they the same specs even in the PowerBook days?
Yup. On at least some recent MBPs the Radeon x1600 has been clocked higher in the 17" than the 15". On at least some of the last revs of the Powerbooks (not sure if all), the 17" had 128mb RAM as standard on the Radeon 9700, though this was available as a BTO on the 15", which otherwise had 64mb.
