 don't know.  talk to henrik.

 don't know.

 there's an fped part *already* defined in
http://git.rhombus-tech.net/?p=eoma.git - fped converts to kicad.

 it's been there for 18+ months joe - why didn't you use it!!

Not anyone's fault. There were a lot of footprints and pads
that had to go in. Most had to be repaired. This particular pads looks the
same as AXP209 but is 1mm wider chip! Hand eye coordination can't fix all
these types of errors in one step. The uSD card for example
is a mirror image! The vga connector pin holes are exact size
of pins with zero clearance and so can't be pushed in.
Never care about such things on first iteration. Just redo asap and move on! :)
