Size of Static Builds

Hi
I'm wondering how big other peoples static builds are with Qt embedded. After trying to only include the minimum required for my app it's still almost 5 Mb. In this configuration it's still set up to use the virtual frame buffer, does that make it bigger? I'm also using QMainWindow and not sure if you're meant to with Qtembedded because it causes you to include quite a lot extra when configuring, is there some other way to make a lighter weight program without using QMainWindow?
Thanks

Try strip -s <yourbinary> and have a look at upx.sf.net.
