In general its good avoid doing this, but this is currently used by
fluidsim & softbody:
 eModifierTypeFlag_RequiresOriginalData

For a reference of places to edit, render branch has the warp modifier
which is fairly recent, for a diff do...

svn diff -r29500:29501
https://svn.blender.org/svnroot/bf-blender/branches/render25 >
warp.diff
