Quick status update:
I can't (yet) get xorg-server to use the Synaptics driver when both xf86-input-synaptics *and* xf86-input-mouse are installed; the "<default pointer>" fake device apparently probes for /dev/psm0 and loads the xf86-input-mouse driver.  I'm not sure how other OSes handle this.  I'll try booting Kubuntu sometime and see what its logfile says.

Really, if the OS vendor configures X.org to use its own hardware detection subsystem, I (e.g. udev, devd, hald, etc.) believe X.org shouldn't have any default devices and should disable any default drivers.  X.org is essentially cutting in front of the Synaptics driver, which could better handle our synaptics device.  Also, nowadays who actually has a true PS/2 mouse?  Synaptics should be the default driver for the PS/2 device.  Who would I whine at for this stuff - the FreeBSD X team? :-)
