Should be supported since commit 95f75e91 which was introduced in Linux
version v3.13-rc4.

Masaki, can you look at those unknown ALPS touchpad identifiers and
provide some information about protocol which they are using?

Basically touchpads with these identifiers are unsupported by last
kernel version:

E7=73 03 50, EC=73 02 02
E7=73 03 0a, EC=88 b3 22
E7=73 03 0a, EC=88 b3 18
