If not using -mm tree just use "psmouse.rate=40" or "modprobe psmouse > rate=40" to check if fix is working for you and let me know.
I have problems with "no keyboard" since Kernel 2.6.9. I am not using a -mm tree and booting with "psmouse.rate=40" does _not_ fix the problem :-( (tested with 2.6.9 and 2.6.10-rc1).
As soon as X is started I have no keyboard. My box is a Acer Travelmate 290 notebook with synaptics/alps touchpad.
