Default first boot activity on Android 2.2?

I'm working on modifying a firmware/ROM for an unbranded Chinese Android tablet i got. When i flash it to the Tablet and get to the lockscreen, unlocking it starts the Setup Wizard - but there appear to be TWO - As Android asks me to choose between two activities - the Setup Wizard and some 'defaultActivity'.

So i wonder - Where and how is this controlled by Android to know what to launch on f开发者_开发百科irst boot?

I had to remove Provision.APK to get rid of the duplicate APK - According to Cyanogenmod's Barebones page it isnt needed. Not much of a proper solution, But thats all i could find lacking any kind of source code for this device.
