JFFS2 from CVS should be fine. It hasn't had as much hard testing as the
stable branch, but I have no particular reason to expect it to be broken on
NOR flash. I wouldn't ship it to a customer before doing some serious
retesting, but you can do that yourself and report anything you find -- I
don't expect anything to break.

There are other things we can do to improve performance and mount time even
more than we've already done in CVS. They're listed in the TODO file, and if
you're likely to actually implement them I'm happy to give more explicit
pointers -- or I can set our salesdroids on you if that would be useful :)
