You have to define NO_REMAP.  5.3 is using regions aligned on 4Mb
boundaries.  If you try to remap, you will get the result you are
seeing.

There are a couple of other places you are going to get hit with.
If you aren't converting to using the the 5.3 opendir/closedir, etc.
you won't have the problem, but then you can't access other file
systems that might be defined in the file system switch.  If you
convert, there is a bad interaction between the GNU malloc routines
and the closedir call.  The symptom is running out of file
descriptors.  The fix is to make a version of closedir that closes the
file descriptor before calling free.
