Only if you change the names of the device nodes too. I.e. make them
/dev/dvb/adapter0/video0  250 0
/dev/dvb4/adapter0/video0 212 0
This way they can even co-exist.

The userland software sees only the device names, it doesn't care at
all about major/minor numbers. So changing the major is strictly
independent from any API changes affecting the clients; changing them
at once would probably add to the confusion already done (do you
always update drivers and userland at once?)
