Forgot to mention in report, I used Kubuntu backports ppa to update KDE on my installation.
I changed 'start' rule in /etc/init/kdm.conf to:
start on ((filesystem
and runlevel [!06]
and started dbus
and plymouth-ready
and (drm-device-added card0 PRIMARY_DEVICE_FOR_DISPLAY=1
or stopped udev-fallback-graphics))
or runlevel PREVLEVEL=S)
This did'nt changed anything, plymouthd is still eating 5% of CPU on background.
