The patch titled
setstream param for psmouse

This patch was dropped because it is obsolete

Subject: setstream param for psmouse
From: Andrea Arcangeli <andrea@xxxxxxx>
I have an infrared keyboard that doesn't work well with Linux. After a bit
of reverse engineering I figured out the command that makes the ps2 mouse
hang is the setstream. This is certainly a bug in the mouse and not in
linux, but I wonder that if Windows works out of the box, perhaps it's not
sending setstream?
Anyway this patch should be a safe approach. It would be nice if you could
merge this, so I won't have to forever patch my htpc kernel with it in
order to use the mouse integrated in the keyboard ;).
