Nope. You could boot a kernel off of it, but that kernel wouldn't know how
to access the drive. We don't use the OF drivers once we've booted. :-(

Your problem is that cu is, by default, waiting for another modem to
connect before continuing. You need to either set that line to "local" in
/etc/tty and re-run ttyflags, or use the dial out device:

Try "cd /dev; mknod dty00 c 12 524288", then chmod /dev/dty00 to something
you can use/what you want. Then try cu -l /dev/dty00.

The dialout lines, which are a feature of the MI driver we copied in our
md copy of it, don't wait for carrier before connecting. So you can talk
to your modem before someone connects.

Take care,
