As it is now, that is correct. However, there are a few options which seem obvious but upon further examination are unworkable:
1. Invert the scrolling for indirect devices. This is probably the sanest and easiest way to do things. However, this would override all configuration of the scrolling in the mouse preferences. For example, it would force two finger scrolling even when the user has disabled the functionality. It would also have its own unconfigurable speed, separate from what is configured in the mouse preferences.
2. Filter out gesture events occurring on trackpads. This will break all two finger scrolling because the scrolling will be "caught" by grail as a gesture and not be processed by X as a traditional scroll event. Essentially, two finger scroll events would be dropped on the floor and discarded without anyone handling them
This leaves us with the complete solution outlined in comment #1, which will take more time than we have available at this point for Natty.
