My kernel config says > ``pseudo-device tun 300''.... Not without teaching the driver to do it itself, no. That's basically what a coning device driver is, is a driver that has been taught. I think the correct approach is to use a clone device, but of course if you put the constraint in that I can't use clone devices, then yeah, static limits require static configuration. You could get non-static fairly quickly by putting Julian's devfs and slice code back in, but of course that'd be pretty politically incorrect (regardless of technical merit).
