Mousedev should provide a reasonable emulation of standard mouse
giving user chance to configure the system properly. There is no need
to task the driver to provide such emulation and therefore I will not
apply this patch.

This happens automatically with Synaptics hardware on newer
distributions (at least Fedora 9 does this). As far as I know
SYnaptics driver does no look for specific product but for a certain
features of the input device and so shoudl work for BCM as well.

The kenel driver should only do as little translation as possible,
allowing userspace to decide how to implement more fancy features.

Does not mousedev emulation work from GPM? Also GPM has evdev protocol
support which should work very well with synaptics-like touchpads.
