RS232 as a Onewire slave "feels" complicated to me. There are a lot of timing 
requirements for both RS232 and Onewire, and I'm pretty sure they don't mix 
very well. Bitbanging RS232 through onewire could work for lower speeds (300 
Baud or so), though.

Which kind of keyboard and display do you want to connect? There is already 
support for HD44780 based alphanumerical displays (available with up to 4x24 
chars) in owfs.

For the keyboard part, a simple matrix keyboard may be connected far more easy 
to onewire.

Kind regards
