Does anyone have a practical working knowledge of the differences between the sensors of the Panasonic G2 and GH2?
DxOMark indicates that the GH2 sensor is capable of one EV greater dynamic range. Does this seem to be so when working on RAW files? Any other observations regarding the differences between these sensors?
Thank you.

Well, the sensor in the G2 is identical to the one of the GF-1. I have the GF-1 and GH-2 here.
Even so it is hard to comment on your question. I've used the GH-2 primarily with the 14-140 and this is not the greatest lens ever whereas I've used the GF-1 with some good to great lenses and reached pretty impressive results with it. Anyway, subjectively I'd say that the GH-2 is just slightly better but it is so at a higher resolution.
DxO normalizes the resolution as far as I know. This normalization results in better ratings even if the DR or noise remains technically similar. Basically think of normalization as scaling down to a certain level - e.g 16mp to 12mp.
If you just look at the results without normalization they will look very similar.
