Its not working quite right. When I add the device and give it the "ALPS_DUALPOINT" flag (or 0), I get all the touchpad events working properly (through the synaptics driver in X). But the stick is
sending weird coordinates through the mouse driver and extraneous clicks through the synaptics driver.
The ALPS_PASS flag just seems to send all the touchpad events to the mouse, and looses all stick events.
I'm not getting psmouse messages from the kernel when its in use. But then again, I'm not really using it all that much. The load time tests report:
alps.c: E6 report: 00 00 64
alps.c: E7 report: 73 00 14
alps.c: Status: 73 00 14
On a side note, seems to me the E6 test should print in decimal, or the comment saying the third value should be 10 or 100 should be changed to hex values.
