Cocos2d on mobile linux

Hi, I have a task of porting a game designed with Cocos2d-x on Android to a mobile Linux platform (I’m on NDA, can’t disclose the exact name of the platform, but let’s say it’s MeeGo derivative). The game is done in Cocos2d-x with C++ and OpenGL ES.

Which code base of cocos2d do I start working off of: Linux or Android ?
Again, this is a mobile Linux platform, so support for touch screen is a must. Does Linux port has support for touch screen or it’s purely desktop ?
Audio framework on that mobile Linux platform is based on Gstreamer.

Any guidance/help would be MUCH appreciated ! Thank you in advance !

Thanks,
Vlad.
