I think it would be good if all uarts were using the same name space and major/minor numbers, but I think the mess we currently have is the result of the tty_register_driver() interface reserving the device number range at driver load time, independent of the presence of devices. I would assume that normal distro kernels always ship with an 8250 driver built-in to allow using that as the console, and if I read the code correctly, that currently prevents another uart driver from registering the same major/minor numbers.
