It is now:

new version 0.0.14 includes mappings for D-pad.

If you have xmodmap installed, the D-pad is rotated as well.

I did not yet put xmodmap as a dependency, since there seem to be many sources it can be downloaded from.

Mine is from:

(/etc/apt/sources.list.d/hildon-application-manager.list)
deb http://mg.pov.lt/770 chinook user other

To those who wish the screen to be rotated right instead of left:
Originally I had the screen rotate to the right, but since I tired my thumb reaching for the back and home-keys, I turned it to the left.
I will make it a configurable option eventually.
