Hmmm, do you have any information about why this isn't acceptable for Nokia? Obviously, I can change my device around any way I like, but that breaks with each upgrade (and doesn't help newbies). I am looking for a default distribution solution in this brainstorm.

Why not treat the few files that need to be fast as special (i.e. link them from the fast flash) and all other files as the normal case (i.e. root default in slow, large flash), instead of the other way around?
