I have the "73 02 64" multitouch/dualpoint device on my Dell E6510. In
a very manual process of modifying the virtualbox-ose PS/2 driver, and
copying bytes between it and /dev/serio_raw0, I managed to piece
together the initialization sequence performed by the Windows driver.
The entire sequence, from boot-up, is attached. I also included raw
event data for three different finger swipes: left-to-right across the
middle, top-to-bottom across the middle, and top-to-bottom across the
right-edge scroll area.
Hopefully this helps in decoding the new protocol.
** Attachment added: "Alps 73-02-04 full initialization sequence, and sample raw event data"
