I don't know the background of the choice of LGPL for the other part of 
the software. Usually LGPL are choosen for libraries that could be 
incorporated in other software that is closed source, apache/bsd or GPL. 
If you had choosen GPL for the main-project and LGPL for 
libraries/drivers and other stuff you think other projects can use - it 
makes sense for an free software project. Then you are using GPL to 
protect the main codeset but widen the use for not so important parts 
(libraries/drivers). Or if you had choosen a closed source, apache/bsd 
style for your main project and LGPL for code that you think other 
projects can use. If you know that your customers want to close your 
code and you don't bother apache/bsd-style of licences are good. If you 
are a small company and don't want Oracle or other large company to 
"steal" or close your code GPL are better.

I think the force for Google to choose a weak licence for Android/Dalvik 
was large telcos  that want to build their own user interfaces and 
drivers for hardware using closed source.
