@Miguel and Adi

I am almost certain your problems are caused by your X tuning and not the driver. Make sure you are using the ALPSPS/2 ALPS Glidepoint interface and not the default PS/2 Mouse. Try using xinput setprops to tune the "Synaptics Velocity Scaling", "Synaptics Move Speed", etc.

If there are still issues, use psmouse-alps-dst-0.4 and enable DEBUG in alps.c. See the run_alps_debug shell function in alps.sh to set the sysfs alps_debug to a "deep debug" level which collects all V5 output from the driver and (on my system) dumps to syslog. It should show 6-byte packets that change linearly in the x/y planes. Please post the snippets of the log when the cursor jumps significantly.
