[Bug 565543] Re: Alps touchpad detected as ImPS/2 Generic Wheel Mouse(in VAIO E series) after the kernel upgrade

[Chris Halse Rogers]

The problem appears to be in the kernel - your Alps touchpad devices
appear to not be tagged with the TOUCHPAD variable.  This means that the
Xorg Synaptics driver won't load for your touchpad - it is set up to
load for all touchpads, and since your touchpad isn't tagged as a
touchpad the Synaptics driver isn't loading.

Finding the precise kernel which broke the touchpad tagging would be
helpful, since this is apparently a regression.  You can find all the
kernel versions which have been released to Lucid on the kernel's
Launchpad page¹.  Finding the last kernel which works, and the first
kernel which doesn't will help narrow down what change broke this.
