Why isn't there a config option for this driver? I just tried to
upgrade to CVS HEAD (bkcvs) from a 2.4 kernel and everything went
smoothly except my mouse didn't work until I appended
psmouse_noext=1. This should not be necessary IMHO. It seems that even
desktop users are forced to compile in this driver, and according at
least to my experience, it can seriously break things. I don't see
what the benefits of the synaptics driver are, and it sounds like
this driver has been causing problems since it was released. The
driver may well stabilize in the future, but right now it should not
be a standard part of the PS/2 mouse driver.
