If the client program is in the business of letting the user set modes
on the device that the device doesn't report on its own, doesn't the
client program really want to allow the setting of arbitrary modes (a
modeline, or enough information to generate a CVT modeline) anyway?  It
seems like having the server allocate extra unused modes isn't going to
win us anything here.
