How do I build a JFFS2 on Disk-On-Modules? Or
any flash-based ATA/IDE devices?
Thanks.

You don't. They have their own wear levelling, journalling flash
translation layer built into them. You just use them as discs.

Certainly wear levelling, and with ECC. This 'journalling' term seems
to be bandied around at levels ranging from block access up to
application data coherency. As far as I am aware the DOM will retain
all but the last 512b sector written in a power fail condition. Does this
count as journalling ?

If it provably will always leave the FTL in a consistent state, then yes,
probably...
