Sidenote: I also have (and use) a Lenovo Thinpad R61i, but
I intendedly deactivated the touchpad in the BIOS and use
the TrackPoint ("nub") instead. But before I did so, I know
that both "nub" and touchpad seem to work "in parallel",
i. e., they are "the same device".

That is the expected result; /dev/sysmouse is a "X thing",
while moused needs a device to be specified with the -p
switch, such as /dev/psm0 (PS/2 mouse), /dev/ums0 (USB
mouse), or /dev/cuaa0 (serial mouse).

In case of the R61, /dev/psm0 should be correct. The
corresponding settings for /etc/rc.conf are:

	moused_enable="YES"
	moused_port="/dev/psm0"
	moused_type="auto"

However, if you plug in a USB mouse, devd will run moused
with the appropriate device name (see above) automatically,
so there's nothing you need to do. Furthermore, I don't
think you need to deal with moused at all when you intend
to use X (and not bother using the dysfunctional vt-based
console mode).

Check /var/log/Xorg.0.log for "mouse"-related lines. There
should be a successful LoadModule entry along with some
settings for the mouse; here you'll also find "sysmouse"
mentioned.

With "pkg info", you can get a list of all packages that
are currently installed.

Good question. ;-)

As you said you're using Xfce, there's probably HAL and DBus
involved, and maybe some configuration file buried within
the /usr/local subtree, filled with XML garbage, that has
been altered by an update...

As you said, you updated a working installation. Maybe this
is due to X having had some changes in the required packages,
so your X installation is now missing something that's needed
to address the mouse? Is xf86-input-mouse present? I cannot
imagine the touchpad requiring anything further (as I have no
longer-time record of using it), but maybe deleting and then
re-installing X would help? However, even with an update, any
"now missing" packages should have been installed, so...
