Absolutely, but I will try again.

Absolutely.  If both input-device and input-device are set to ttya in OF, I
can boot to NetBSD and operate normally through zterm.

That could be, but wouldn't that would occur if both input and output were
set to ttya?  On the otherhand, if NetBSD detects kbd, I could see where it
might try to change the baud rate for ttya for display to zterm.  What baud
rate would it try to change to?

I am not sure, but I thought I was also not able to input blindly through
kbd when output-device was set to /chaos/control and input-device was set to
kbd.  I have to recheck this, though, as I had difficulty operating blindly,
trying to remember things while I was setting up NetBSD.
