Cool :)

Yes, they should work ok now, just make sure you have updated the driver
within the last day or so.

Yes, that was a nasty bug nailed early on - there was jump detection in
the code but it only checked one direction, wrapping the jump size in an
abs() made things a lot better.

Yes - the defaults make the cursor slow for me too.  It would suggest
playing with:

hw.synaptics.scale_x
hw.synaptics.scale_y

The lower the numbers the faster the cursor will move.  I set both of
them to 4 in my sysctl.conf - the defaults are 16.  I am guessing they
were set back in the days when the trackpad resolutions were a lot
lower.  I think it would be wise to leave the defaults as they are on
the basis it is better to have a slow mouse initially and give people
the control to increase the speed rather than have a cursor zipping all
over the screen making it impossible to use.
