Looks like x11-drivers/xf86-input-synaptics only queries the ClickPad 
property on Linux:

src/eventcomm.c: event_query_touch(InputInfoPtr pInfo):

#ifdef EVIOCGPROP
     SYSCALL(rc = ioctl(pInfo->fd, EVIOCGPROP(sizeof(prop)), &prop));
     if (rc >= 0 && BitIsOn(&prop, INPUT_PROP_SEMI_MT)) {
         xf86IDrvMsg(pInfo, X_INFO,
                     "ignoring touch events for semi-multitouch device\n");
         priv->has_semi_mt = TRUE;
     }

     if (rc >= 0 && BitIsOn(&prop, INPUT_PROP_BUTTONPAD)) {
         xf86IDrvMsg(pInfo, X_INFO, "found clickpad property\n");
         para->clickpad = TRUE;
     }
#endif

EVIOCGPROP is a Linux ioctl.  Someone'll have to write a patch to query 
the FreeBSD device for that property.  I guess I'll see how hard it'll 
be to add that bit.
