Wouldn't it be easier to forward-port uCLinux to 2.4? Didn't someone 
already do that, in fact?

JFFS1 will be easier. JFFS2 is possible but may be a lot of work. The dcache
thing should be the biggest problem - and that's possible to work around. I 
wouldn't backport the whole of the dcache thing to 2.0 - that would involve 
completely rewriting the VFS. Just provide internally to the JFFS2 code 
sufficient dcache stuff for it to work. Pretend dentries are JFFS2-internal 
data structures.
