IIU the SUSv4 description C, and given that a newly opened console is
always setup with the default termios settings anyway, we could simply
set O_TTY_INIT to 0 and be done with it:

  If path identifies a terminal device other than a pseudo-terminal, the
  device is not already open in any process, and either O_TTY_INIT is
  set in oflag or O_TTY_INIT has the value zero, open() shall set any
  non-standard termios structure terminal parameters to a state that
  provides conforming behavior.

Right?
