Do not use synaptics extensions by default

[Pavel Machek <pavel@suse.cz>]

..aka "make synaptics touchpad usable in 2.6.1" -- synaptics support
is not really suitable to be enabled by default. You can not click by
tapping the touchpad (well, unless you have very new X with right
configuration, but than you can't go back to 2.4), and touchpad senses
your finger even when it is not touching, doing spurious movements =>
you can't hit anything on screen. Without synaptics extensions
everything works just fine. You can reenable synaptics support using
commandline.

Plus it documents psmouse_noext option.

Please apply,
								Pavel
