pegasos II boot over serial console?

[Håkan Johansson <f96hajo%chalmers.se@localhost>]

Hello,

I'm trying to boot NetBSD 5.0 on a Pegasos II over a serial console.  The 
boot process stops (or at least nothing more is shown) after 'pegasospci0 
at mainbus0'.  The initial announcement of ofppc booting on a Pegasos II 
had 'Switching to COM console at speed 9600' right after this.  I'm 
wondering how to configure a kernel to successfully use the serial 
console?

I've tried to add to the GENERIC kernel configuration

options         CONSDEVNAME="\"com\"",CONADDR=0x3f8,CONSPEED=9600

with variations of 2f8 and 115200.  Do one need to do other changes as 
well?

Currently, a cross-compiled kernel gives the output shown below.

Thanks,
Håkan
