I don't know where JFFS2 hits the wall, theoretically or practically, but I do 
know that people are using YAFFS on 6GB partitions. 

YAFFS does use u32s internally but only thinks in pages and 32-bits worth of 
pages go a long way.  You'll hit practical limits (like RAM required) long 
before that.
