What kind of machine is this?  Please attach full "dmesg" output
from a normal boot and an acpidump.

Is this a regression or did this machine always behave this way?
Does the 2.6.32-based kernel in squeeze exhibit the same symptoms?
(Generally it is supposed to work fine on wheezy/sid.)

How about 3.4.y from experimental (or some other kernel 3.3-rc7 or
newer)?  If it exhibits the same bug, please send a summary of
symptoms to linux-input@vger.kernel.org, cc-ing Seth Forshee
<seth.forshee@canonical.com> and either me or this bug log so we can
track it.  Hopefully someone upstream will be able to give hints for
finding the difference between the cases where the touchpad is
properly detected and not so (e.g., by adding some printk calls).

Hope that helps,
Jonathan
