So, I was trying to look at this... That code in the xserver hasn't
changed in forever.  I'm trying to find someone who can explain to me
why it does that.  One thing that I find curious is that in the xorg log
that you showed, the mouse seems to report a lot of serial options.  I
don't see that in my setup.

Right now, I'm running with AllowEmptyInput on, so kbd/mouse driver
configs are ignored.  I'm disabling moused on psm (glidepoint touchpad)
and configuring it with the "synaptics" driver (which AllowEmptyInput
won't ignore).  usb mice are added via hal, currently via sysmouse.

rc.conf:
#moused_enable="YES"
#moused_nondefault_enable="NO"
moused_flags="-3 -m 1=4" # This was for the glidepoint with moused 
moused_ums0_flags="" # and this made it not remap external usb mice

/boot/loader.conf:
hw.psm.synaptics_support=1
