You have two problems at once. They both reflect the fact that /etc/ttys
isn't set up right.
The first is that you don't have a getty turned on for tty00 or tty01,
so when NetBSD comes up, you loose all input ability. The other problem
is that the line for ttye0 is still on, even though the internal video
doesn't get configured if you're on a serial console.

The new version of the serial driver will have this feature, though
you'll need a new booter and also to change the line in /etc/ttys. If
you just want to connect at the faster rate, just change the baud rate
in the line in /etc/ttys. I don't recomend 57600 for serious data
transfer in. 38400 seems ok.

The FAQ, at www.macbsd.org, certainly helps. :-)
