Yes, you should really do that :-) I'm just flipping one switch and then
my machine is booted about a minute later and I don't have to touch
anything but the powerswitch. Automatic reboot after panics is also
working without problems.

No. I'm doing ppp at 57600 between my main pc532 (klondike) and my test
machine (dummy). On my i386 X-Terminal I have running getty on vt00, X
on vt01 and some sort of tip on vt02. The tip on vt02 connects the
i386's cua1 with the console of klondike. On klondike's tty01 I'm
running a cu to the console of dummy. Klondike's tty02 is connected to
dummy's tty03 for ppp. The tcp/ip connection between klondike and xtk4
(the X-Terminal) runs over a 50 kbyte/second plip link. I'll try running
getty on dummy's tty03 and cu on klondike's tty02 this weekend. This
should be similar to your setup.

Could you try something other then 38400 as the speed for your second
getty? Are you sure the rest of the terminal settings is correct? You
might get 7E1 on your second line. I think std.pc532 only changes the
terminal setting for the console device to match the monitor's tty
settings. Did you have a local patch to change the default terminal
settings with your old kernel?
