Basically you will have to modify device_added(const char *line) in
config/devd.c to create a new InputOption "object" and set the "driver"
option to "vmmouse" (assuming that's the driver name) using
input_option_new().

I did my own implementation of config/devd.c (I think others have also,
but I think they're all basically similar) different from the one
currently in x11-servers/xorg-server/, it uses a function table to call
a function for a given const char *line passed to device_added() to make
a decision about what driver to attach.

https://github.com/ScoobiFreeBSD/freebsd-ports/blob/xorg-synaptics/x11-servers/xorg-server/files/patch-config_devd.c

You'd add an entry to hw_types[] for the device node created by devd(8),
adding a new function to fill in the InputOption object depending on
information from the system.
