I've just done this on Eagle and will build it tomorrow as I'm off to work shortly.

Might be useful to other people.

Did you take a look at this http://ics.nxp.com/support/documents/interface/pdf/an97055.pdf for Levelshifting with MOS-Fet's can save some Resistors and space.

To be honest I haven't but simple transistors and resistors are dirt cheap so might be cheaper with these. I will look at the alternative though. I want to add IR IN, PS2 keyboard and real time clock to a 40 pin TFT shield plus maybe an IR output. With all those it might well work out easier to use a level shift IC in the end.
