Problem resolved upstream -- details here: https://bugs.freedesktop.org/show_bug.cgi?id=88609
An easier temporary workaround is to create a file in /etc/modprobe.d/ called psmouse.conf and put the following line in it:
options psmouse proto=imps
Then do sudo update-initramfs -u
I'm hopeful that the patch from freedesktop.org will be backported to Trusty's kernel soon.
