On the i386, *none* of the TTY devices work with pstat -t.
I looked into this last night. The solution is nontrivial, because
the pointer to the tty struct is now kept in each tty {pseudo-,}device
driver's softc struct. The type of the driver's softc is specific to
that driver, so there is no generic way for pstat to get to the tty
struct.
