Not sure about any existing "fast" implementation, but mounting a JFFS2
partition is about scanning whole partition. You may optimize some
thing, but you have to scan anyway.

I would suggest to create a small JFFS2 partition with kernel so that it
is mounted quickly by the bootloader. Then you could mount it to /boot
of your "main" partition.
