devel with QT4

Dear all,
I want to devel my application for mini2440 using QT4, currently I cross
compile and everything works correctly, but for speed up the development I
need to test it on my x86 linux before crosscompile...

I try the qfvb option while configuring QT using also x86 as target but the
applications seems compiled for x11 and not for the virtual frame buffer.

Are there anyone how can help me with the correct procedure for the qt
configuration on linux x86 with frame buffer?

Thanks
