Yes, they use the same driver, but your problem starts when getty
exec's login.  So I suspect that login is changing the characteristics
of the tty.

I just looked at the termios manpage, and it is possible to set the
number of stop bits to 1 or 2 (see the CSTOPB constant).  It is also
possible to set the number of databits (see the CSIZE constant) to
anything from 5 to 8.  It could be that getty sets csize and cstopb to
liberal values, like 8 data bits and 2 stop bits, and login sets one
and/or the other to smaller values.
