Hahaha you beat my post by 2 minutes.

What modifications did you make for the port? I only found one missing dependency, and that was for NTFS support, so i just left it out. There is definitely room for a bit more specialization for the N900 from the upstream source.

Things i noticed in the original PhotoRec app that need some tweaking: reduce curses menu size so it fits better in the X Terminal, remove some of the prompts for options that are redundant for the N900 or Maemo, default to the MMC for output of recovered files, and nicify it so that it doesn't make the entire device unresponsive while it's running.
