I just bought a HP Revolve 810 G1 laptop. (This is a convertible
ultrabook, normally sold with Windows 8.) The touchpad seems to be
another ALPS touchpad, not yet recognized by the kernel; I tried the
Debian package of 3.12 and linux-next-20131224 compiled from
source. Without the proper driver, it is unusuably sensisitive,
registering clicks when my hands are well away from the touchpad.
The relevant line from dmesg is

[    2.776630] psmouse serio4: alps: Unknown ALPS touchpad: E7=73 03 0a, EC=88 
b3 18

Should I try hacking drivers/input/mouse/alps.c to see if one of the
existing protocols works?

Thanks,
