Lazarus LCL/Qt-embedded running on qvfb:
http://users.telenet.be/Jan.Van.hijfte/qtforfpc/qvfb_lazarus.png

Qt:
===
downloaded, untarred in /somedir, configured & 
compiled qt-x11 and qt-embedded. (may take a couple of minutes :-)

x11: ./configure -prefix `pwd` -opengl -xrender -xcursor -xrandr -qvfb
embedded:./configure -prefix `pwd` -qvfb

qvfb:
====
after compilation, x11-qt should contain qvfb in subdir bin.
run qvfb

FPC Qt4 Binding:
=============
cd /somedir
tar zxvf qtopia_qt4pas-V1.68_Qt4.4.3.tar.gz
cd qt4pas-V1.68_Qt4.4.3/
export LD_LIBRARY_PATH=/somedir/qt-embedded-linux-opensource-src-4.4.3/lib
sh compile_lib_qtopia.sh i386
cp libqt4intf.so /somedir/qt-embedded-linux-opensource-src-4.4.3/lib

Lazarus:
=======
cd /svn/lazarus
export LD_LIBRARY_PATH=/somedir/qt-embedded-linux-opensource-src-4.4.3/lib
make PREFIX=/usr clean all LCL_PLATFORM=qt OPT="-dUSE_QT_44 -dQTOPIA"
./lazarus -qws

Note how the define QTOPIA solved your problem
