The console drivers now understand arbitrary rate requests and the core tty code has for years supported doing the mapping for arbitrary baud rates as well as back mapping them onto "classic" B9600 type encoding when possible. That would also various devices with insane baud rates where someone was too cheap to fit an extra crystal.
