I don't think this should be enabled by default, since there
is no ps2 connector on the board, and the pins can be used
in a different manner too.
I do think it is useful to have it in there as an example for people who want to use
it, but commented out, please also add a comment stating that using ps20 conflicts
with using the hdmi connector.
Regards,
Hans
