commit 6c4a643d632c6cff647c5099bd450d1e417903ea

    ARM DPM: disable some nyet-ready breakpoint code
    
    Until we manage breakpoints at runtime (patches not ready for 0.4)
    the only way this code should touch them is to disable them at server
    startup (a previous debug session may have left them active).
