looking in dmesg output for subsets of that I find:

3.417773] input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio4/input/input5


[    3.090864] psmouse serio4: synaptics: queried max coordinates: x [..5694], y [..5048]

[    6.646764] psmouse serio5: alps: Unknown ALPS touchpad: E7=10 00 64, EC=10 00 64

all of which I take to mean it is an alps touchpad that is synaptics compatible. Any
pointers on how to figure out what its capabilities are? (other than just trusting the
synaptics driver to figure it out, which I've already tried but don't like the result).

I've googled for some of those values, but didn't turn up anything meaningful (to me).
