Sadly no. This was a subject of much debate, but Russel King insisted
that ttyS would be used only for NS16550-style UARTs. In the past, the
pmac_zilog driver hijacked that major/minor anyways, but it was later
changed to use its own major/minor (and ttyPZ). (I don't remember when
that change occurred, but it should be pretty easy for you to find out
if you care.)
