Now I reply to my own mail. Annma was so kind to help me finding a solution on 
#kde-devel. The point was, that the enabled state of those fields has be set 
before the dialog is shown which is not possible within the designer and thus 
has to be done from the calling c++ code. I did just that and it worked. 

To document it:

// create the dialog
KConfigDialog* dialog = new KConfigDialog(this, "KThinkBatSettings", 
KThinkBatConfig::self(), KDialogBase::Plain);

// instanciate the generated (by KConfig XT) prefrences panel
Prefs* prefs = new Prefs(this);
assert(prefs);

// Ensure, that an setting which depends on another is only 
// activated, if the requirements are fulfilled
// !!! This solved my problem !!!
prefs->kcfg_AcpiBatteryPath->setEnabled(KThinkBatConfig::enableAcpi());

// add the preferences panet to the dialog
dialog->addPage(prefs, i18n("KThinkBat Preferences"), "configure");

//User edited the configuration - update your local copies of the
//configuration data
connect(dialog, SIGNAL(settingsChanged()), this, 
SLOT(slotUpdateConfiguration()));

// Show the dialog
dialog->show();


Regards,
Tobias
