Bug#622707: bug 622707 seems resolved upstream
Just a little update:

This is true for the synaptics touchpad, but it causes a terrible problem:
I started using Linux on this laptop since I started with Linux in
2008 with Ubuntu 8.04 based on the 2.6.24 kernel.
Ever since kernels higher than this one I've had an issue of keyboard
repeat: keys behave as if they would still be pressed when released!
Usually I just accepted this problem (which happened on occasions).
The solution was simply to press another key to "un-jam" the one
repeating itself. You can imagine this being very annoying when the
delete or backspace key gets jammed...
This is an old problem in the kernel and X :
Unfortunately for me, by passing the kernel the nomux option, now I
can't un-jam the key that keeps repeating!...in fact, I loose full
control of the keyboard and touchpad when this happens...only the
power button works (alternatively I can use an USB mouse to try to
remedy the situation).
I don't know what to do to solve this problem...the first link seems
to have some ideas, but I don't know if work has gone into solving
this rather obscure issue.
I'll probably go back to using evdev to handle my touchpad for the time being
