I fail to see what was academic about that discussion. Is it academic,
if you pass /dev/hda1 (empty partition) or /dev/hda (whole disk with
root partition) to mke2fs? Try it and tell me again. :-)

If it was formatted correctly, it should get mounted. But I have no
idea, what "it's all formatted correctly" or "JFFS2 sees a bunch of
data" means. Try doing a trivial format (eraseall /dev/mtd<n>) and
mount that. If that fails, show me that the partition has all 0xff and
the jffs2 messages and I will have a look. Until then, I consider this
to be pebkac.
