I built a kernel with these changes, copied it to my 425t, and did the following:

- Added wscons=YES to /etc/rc.conf
- Uncommented screen 0 line in /etc/wscons.conf
- Set console to Local instead of Remote in Configuration, RS-232
- Shut down machine
- Booted my new kernel

It showed the kernel startup messages on my HPA1659A!

Unfortunately, it then panicked:

    panic: cnopen: no console device
    Stopped in pid 2.1 (init) at netbsd:cpu_Debugger+0x6: unlk a6

I’m going to re-comment the “screen 0” line in wscons.conf; I didn’t need it on the 433s.
