Correct. It is only needed for getting the mouse work in the
console. With vt having replaced sc as the console driver,
the console functionality has seen several facettes of decay,
which is sad, but seems to be required to keep X happy.

Still there is one thing I seem to remember from the thread:
At some point, you said that you've obtained debugging data
from the psm driver directly (not via "moused -d"), and with
the hw.psm.synaptics_support="1" setting in /boot/loader.conf,
you did not get any reaction from that channel. This is strange.
Even though X input does not need moused support, is surely
needs psm support (via the "sysmouse" hook). I'm not sure
this looks entirely correct - but I don't have (and don't like
to use) touchpads, so I cannot provide any further ideas.
It's just my gut feeling, resulting in memories of low-level
programming done decades ago, that you should at least get
_some_ kind of reaction from the psm driver whenever an event
happens on the touchpad.

Make sure you have xf86-input-synaptics and libsynaptics installed.
X should then detect the corresponding device automatically and
load the appropriate drivers and subsystems.

Maybe it was on an older FreeBSD version? Decay... ;-)
