I'm not sure about this. I know that the synaptic driver can use multiple hardware drivers. In my system, I am using "appletouch.c" which I believe has support for all modern macbook, macbook pros, powerbooks, and ibooks. There are branchings (if statements) in the driver that execute different buffer reading procedures depending on how the trackpad identifies itself.
There may be an intermediate driver that could be different though. That would make sense as to why the two finger jumpiness is not present with all macbooks. Thanks Nikos for testing out the jumpy cursor thing. Someone with a bit more experience with reading trackpad input could give some insight into the best way to read sensory data. Right now I think it is just a linear weighting (ie every sensor has equal weight) but I think that the "primary" sensor that your finger is connecting with should have a higher weighting so that the cursor doesn't jump around as much... but even that doesn't exactly seem right.
