I need to work on several projects so will not have time to look at this again this week. I rebased our work on Kevin Cernekee's 14-part submission to linux-input. His patchset cleaned-up/refactored a lot of the messier code along with a more comprehensive init sequence for the Dell E6XXX series. Ben's V5 init sequence is no longer necessary. The new dlkm is at [1].

The one final step that needs to be taken is to reconcile florin9doi's init sequence for my Dell N5110 and a Fujitsu a512. The systems have the same E7/EC signatures but appear to have different init sequences. When I use the Fujitsu a512 init sequence, my system is stuck in PS/2 3-byte format and, apparently, the converse is true for the Fujitsu.

I have re-added the alps_debug sysfs interface to toggle packet debug and switch between the new V5 (was V6) init sequences for the N5110 and a512. This can only be done by setting the alps_debug bit and rebuilding; I couldn't get it to work on-the-fly.

We are almost to the point of a submitting a final patchset to resolve a LOT of ALPS touchpad bugs.
