OK..
I added hw.psm.synaptics_support="1" too my /boot/loader.conf and
rebooted.  I also have:
   moused_enable="YES"
   moused_port="/dev/psm0"
   moused_type="auto"
in rc.conf.  After reboot things are still fine.  Mouse is available on
console.

I make the above changes to xorg.conf.  Now X wont come up.  It
complains of no access to /dev/psm0 (device busy)!?  I leave all of the 
above in xorg.conf and revert back to 'option "Device" "/dev/sysmouse"' 
and X comes back up.... but I can see no noticeable difference in mouse
behavior.  Using xev (which I am unfamiliar with, other than to watch
the events fly by)... offers nothing that looks new.

Then I decide to remove the hint I mention above... no mouse at all in
console... not reported in dmesg either.  X of course complains of no
/dev/psm0.

Running X as root in any of the above situations yields no better results.

So... while my machine did not fail in the same fashion as yours...I
can't seem to get 'synaptics_support' working.

If you need me to try anything else let me know.

HTH.
