Hmm. Can't help with this, I bought ethernet cards instead.

For a PPP connection something like this should suffice:

One one machine run:
/usr/sbin/pppd local 115200 crtscts 192.168.1.1:192.168.1.2 passive /dev/tty00

on the other run:

/usr/sbin/pppd local 115200 crtscts /dev/tty00

That should set up a PPP connection between the 2 machine. On the i386 
you will need to substitude /dev/tty00 for /dev/tty01 if you are using 
COM2. This assumes that the machines are attached via a fully connected 
serial crossover cable.

You will need the setvideo binary. The sources for this are available 
on the NetBSD FTP site:

ftp://ftp.netbsd.org/pub/NetBSD/arch/arm32/misc/misc-src-riscpc.tar.gz

You need to run setvideo just before you run startx.

BTW it may be work upgrading the arm32 machine to 1.4.1 as you can then 
use the X server which comes with the distribution which is a lot more 
reliable than Xarm33.
