I have a strong suspicion that we'll never see chips without a 'major' 
erasesize. Making all clients (such as JFFS2) deal with variable erase 
sizes is possible, but IMHO suboptimal. If we can avoid that complexity, it 
would be nice. 

Perhaps, however, we should provide a way for clients which _do_ know about 
variable erase regions to write to partitions which don't have a 'major' 
erasesize.
