 We solved this in N800 with the attached patch.

 Just mount JFFS2 with -o rpsize=8000 and it will reserve _about_ 8Megs of
 space for root. If you want other uids/gids to use that, add them too (see
 patch's header).

 Because JFFS2 becomes dead slow when it has no space, I recommend you to
 have reserved pool like 8-16 Megs. Note, slowness when no space is normal
 for any flash fs because it has to do a lot of Garbage collection in those
 conditions.
