Hm, ok.  An alternative to using the system buffer would be to make
JFFS[23] use a write buffer for those devices.  It's already done on
NAND which has some special handling.  The support for ECC'd NOR
probably matches more closely what you'd want to do.  Take a look at
wbuf.c.

Well, if it's better than the original we can always take yours and
replace what's there.  Send it on, performance gains are always
welcome.  I'm sure there are others interested in what you've done that
will review the code.
