Well, poor you. :-)

I'm not sure to which kernel you should better port, probably yes, the
latest 2.4, but I consider using old kernels as very bad approach, even
silly in some respects. 

Hundreds of bugs were fixed since 2.4.10. VFS also had many bugs, and
the dependency of JFFS2 on VFS is obvious. So, if you meet a problem,
nobody will assist you finding bugs which were already fixed several
years ago. Will you find them yourself? - no problems, but digging such
an old code can't be interesting, it will barely increase your skills or
bring any professional satisfaction. Its much better searching bugs in
modern kernels. That's your choice - I'd better change the employer :-)
