I am very impressed Maemish...
you are on exactly the tangent I would be taking...given the exact same scenario..
and you are doing it wisely ...like tiptoeing gently through a garden in bare feet ....looking at what impact every footfall makes...and trying to foresee and anticipate potential impacts from future footfalls before you put your toes down into the garden in front of you ..

Much saner an option than stomping through with boots on...wondering why there is damage...

you are definitely looking at the situation inside as a holistic one.
and you are peeking in to see what potential damage to other functions may occur from just one package that is a subtle variation of another...

ooooh!
isn't it exciting?!?!
its like a good puzzle...or trying to diffuse a bomb...
Or better yet ...like a game of "Operation" ...don't touch the sides! ...bzzzzk!
hahaha
ah envy you your fun...
its been some time since I had a maemo program I wanted to get to work so badly ...that I mucked around as you are now..
I am content with what works ...have been for a while...
I am sure that too shall pass...

Anyway...
I think you are approaching the problem the best way...
Hm.
who was it now who worked and did all the "cute-___" progs for maemo again?
HIS brain is one you definitely want to pick...
Help you need on the "cute-___" series ...was his baby...
I'd be finding his home address and camping on his doorstep until he helps you ...he did after all make them ...
Just nudging you in the best direction and the best maemoian who could help....considering...

Or ..do it yourself...as you said...you got it before...
Did you write down exact instructions on how to? would make it easier to replicate the results...maybe not as fun...but it would shave a great deal of time off ..
