[solved] kdemod 4.2.4 and kernel 2.6.30 lost effects

Question

Hello,
I wonder is anybody encountered similar problem (see topic)?
my system
today installed official arch kernel 2.6.30-ARCH
so my updated system looks as follows:
system:
Arch linux i686 up to date (system update 06-23-09)
kdemod 4.2.4 (up to date) i686
nvidia video card Go 7400
nvidia driver 185.18.14
file system: xfs
RAM 2GB
kernels:
2.6.30-git1 up to -git16 (installation of nvidia driver fail on git-17 and above due to the new and no doubt exciting changes to the kernel)
or
2.6.30-zen1
or
2.6.29.5
or
2.6.30-ARCH (official crom core)
booting to any of 2.6.30 kernels will cause lost of transparency effects, window decoration effects, smooth transition from login screen to the desktop)
booting to 2.6.29.5 will restore visual effects.
Because all the kernels have nvidia module installed, and problem identical persists with different nvidia drivers i assume that this is related to the changes in the kernel.
No erors in
/var/log/Xorg.0.log
/var/log/errors.log
/var/log/messages.log
I did post similar information at Chakra site but problem may not be related to kdemod 4.2.4 but kde 4, so that is why I decided to post about this issue here.
Thanks

I have exactly the same issues.
kernel: 2.6.30-ARCH
KDE: kdemod 4.2.4 i686
NVIDIA gforce 7400go
nvidia driver 185.18.14
and no composite.
Failed to activate desktop effects using the given configuration options. Settings will be reverted to their previous values.
Check your X configuration. You may also consider changing advanced options, especially changing the compositing type.

has no effect.
I tried many options in the xorg.conf, also the nvidia-173.14.18-3 driver, but no effects yet.
OpenGl works flawlessly.
