 So it is a matter of implementing the right callback in BFS to support
 FIBMAP/FIEMAP. Same for ntfs3g.

ntfs3g does implement bmap. Problem is that the only way to access this from userspace is FIBMAP which cuts to 32-bits. FIEMAP is implemented as a different ioctl rather than piggybacking on bmap.
