I'm assuming you're talking about the i386 port (remember, NetBSD is on
a bunch of platforms).

Easily done on NetBSD as well, just replace the pc0 driver with the vt0
driver in your config file (i think the GENERIC config file has vt0 line
there waiting for you to comment it out).

Or even easier, compile screen.
