I'm think ttyS2 is the one you need, ttyS0 is keyboard/mouse port, 1 is
printer and 2 is serial console (I think!!!),

On my DS5000/200 I have no graphics card at the moment, and all I do on it
is boot 6/tftp and I don't pass command line at all and it seems to work,
(I've messed with init.d scripts)...

so as a recap you plug the serial line into port 3 which should be ttyS2
.... I recommend moving over to a full serial console with the 
setenv console s ( I think again)... at least until framebuffer and stuff
support arrives ..
