QFormLayout and consistency in systemsettings kcm modules

Hi everybody

I noticed that almost all kcm modules use QVBoxLayouts for laying out our 
beloved configuration widgets. the "almost" there is due to (at least) the 
following exceptions:

kdebase/workspace/kcontrol $ ack QFormLayout
kdm/kdm-gen.cpp
35:#include <QFormLayout>
51:     QFormLayout *fl = new QFormLayout( box );
74:     fl = new QFormLayout( box );
107:    fl = new QFormLayout( box );

input/mouse.cpp     //---- Advanced tab
51:#include <QFormLayout>
201:    QFormLayout *lay = new QFormLayout(advancedTab);
322:  QFormLayout *form = new QFormLayout();

style/kcmstyle.cpp  //---- Fine Tuning tab
46:#include <QtGui/QFormLayout>
232:    QFormLayout* page2Layout = new QFormLayout( page2 );

fonts/fonts.cpp //----- Subpixel configuration
25:#include <QFormLayout>
231:  QFormLayout *layout=new QFormLayout(mw);

In fact if you pay attention, the layout in each of the preceding cases is 
slightly different from the other cases. In particular the vertical alignment 
of the label with respect to the widget on its right is messed up; the text 
fields do not align correctly, they are a few pixels off, it seems that the 
label and the widget are Top aligned...
At first I thought it was some issue with the qt-style I am hacking with, but 
the problem indeed is visible in all qt styles. 
Is there any clever flag to can pass the QFormLayout to make it align stuff 
consistenly with the other layouts? Otherwise, does anybody have any objections 
if I turn all QFormLayout to QVBoxLayout? luckily they are not that many and 
the other way it looks much better. 

Thanks
