Is that all? Mine reads:

I take it then your keyboard is not connected via USB. Well, try the
attached patch and test program (to compile just run 'make ,,test').

Then insmod the changed driver, and run the test program as follows:
./,,test > /tmp/dump
wait a few seconds, maybe press touchpad button a bit and move the
finger over the touchpad, kill the program with ctrl-c, bzip2 the file
and send it to me (privately please, not on list).
