I think that first of all this is a design problem. If you want smaller
boot time, you need to figure out what exactly you need during the boot
time and create minimalistic partitions. Anything else can be mounted
later on.
Moreover, for the stuff that is effectively read-only I would recommend
using read-only filesystem such as cramfs with a read-only translation
layer, like this one:

Well, that all doesn't mean you shouldn't use SUMMARY for your JFFS2
filesystem. :)
