As far as I know, jffs2 doesn't support writable mmaps.  In the debian
ports, we add some special magic to tell apt not to use them (
http://wiki.laptop.org/go/Installing_Debian_as_an_upgrade ); and the
following code from pilgrim appears to do something similar:
  	    echo "  - Configuring RPM to not use writable mmap (as jffs2
don't support it)"
	    mkdir -p $INSTALL_ROOT/etc/rpm
	    cat <<EOF > $INSTALL_ROOT/etc/rpm/macros.rpmdb
%__dbi_cdb create private nommap

It's probably worth reading through the pilgrim
'streams.d/olpc-development.stream' file to see if there are other
fixes you are missing.
