I am not really an expert in this area.
For personal interest I looked yesterday into the libvgl (e.g.
VGLMouseStatus(1) and the other functions mentioned there). It seems to
cooperate with syscons including mouse support.
Somehow (for me "by magic" - I do not know how) Xorg seems to recognize a
system mouse that is configured for the terminal. If someone explains this
magic it may be helpful for you.
My interest came from another angle. I tried to find out whether FreeBSD's
infrastructure does not support displaying of more than one VTs at the
time, as someone claimed. I would like to configure my laptop to use the
small internal monitor as a text console while the external monitor is
serving X.
Regards
Peter
