Note, that not just OSM, but all the major API tiling schemes, start with the upper-left corner as the origin.

The TMS spec starts with the bottom-left, as this makes more sense in "geographic space", the gmaps tiling et al is based in "image space".
(IMO, this is also a reason to be somewhat sceptical of standards arising out of the GIS space, which can _purposely_ ignore what's already in common practice. Ok </rant>)

Anyway, as Tim said, it's only a small javascript fix to get this working.
