Bummer. Upon further reading I see the difference in flash devices now. 
Do you think UBIFS could replace JFFS on the Freerunner? Is there a 
benefit? Or is there not enough wiggle room on the FR for caching? It 
seems better overall [1]. Would it be possible to replace it yourself 
with the appropriate kernel modules etc?

Ok enough questions ;-)
