No VGA out or PS/2 in?

I've been looking at building a board around the propeller chip much
like the Briel Pocket Term project, but I'm not really crazy about the
whole cog idea or spin. I want a microcontroller that can at least
run a tiny version of linux with an ethernet stack and which has
ethernet integrated into the microcontroller chip (so far so good...
but...)

I notice on the Linux Stamp there is absolutely no mention of any VGA
or composite out, or any PS/2 mouse or keyboard in, which are trivial
to implement with the propeller chip. Why not?

Why is there no video out or PS2 in on the Atmel? Kind of impossible
to have an interactive session with it as a self contained standalone
computer without these. Talking to it via ethernet / usb is fine, but
you need a whole other computer to do so.

That's like building a car you can ride in and use, as long as you
have another fully working car to pull it along with a chain. Maybe
useful to have such a car to hold down the grass on your lawn, and you
can sit in it and pretend, but not useful for going to fetch your mail
in town with.

Has anyone tried to implement these, and if not, how hard would it be?

PS/2 is really just serial and the at91rm9200 has lots of serial
ports. As far as graphics output there is graphics hardware on the
at91rm9200. The Linuxstamp is not intended for applications that need
a PC like interface.

There are many arm processors that have dedicated graphics hardware,
have a look at something like the TI OMAP 3440.

thanks,
Paul
