Hi,

Since we now have fully updated ALPS drivers in raring, I thought it was
about time we SRUed this change to quantal so we can fix a number of
issues that we're experiencing with ALPS touchpads. This enables support
for a number of Dell and other laptops on the market, some of which have
been using unofficial dkms packages in order to get working.

Kent Baxley has tested this patch set extensively, on a number of
systems. Systems that reverted to PS/2 generic mouse before are
supported as ALPS mice with these patches.

Please consider this for inclusion and let me know if there are any
questions.

I have not looked at the patches. The number of changes is relatively high. But
then it is all contained in one driver for which regressions would have been
noticed in testing quite quickly. So if "extensive" also included older models
using ALPS, I would tend to agree with getting it into Q.
