This sounds like a hen-and-egg problem to me. Until ext2 is really
known to support larger files (including in the infrastructure,
e2fstools), there is apparently little motivation to modify the Linux
kernel for good. OTOH, it seems the ext2 people would not modify the
file system until the VFS layer can handle it.
