Just have a look at my menu.lst file attached and look for the "i8042.reset", that must be added in the options sequence for each kernel you want to use (2.26.7.11-generic is working for me right now; I don't know if it would work for previous kernels).
For commodity, the option should also be inserted in the "defoptions=" line, so it should be added automatically for any kernel that will be installed after future upgrades.
