Oh yes, I did read it in your last answer. I think on one side, this
can't be the "true" in my case, because in the Xfree.0.log everthings
looks like hw acceleration is used fine:

...

        Solid filled rectangles
        8x8 mono pattern filled rectangles

        Dashed Lines
        Offscreen Pixmaps
        Setting up tile and stipple cache:

                17 256x256 slots
                6 512x512 slots

(II) SIS(0): Direct rendering disabled
(WW) SIS(0): Option "CalcAlgorithm" is not used
(**) RandR enabled
...

On the other side, you might be right - what else could make the
X-Server so busy? But why does it do this even though the
XFree86.0.log says hw acceleration is being used?

Yes, just before my SuSE-Update, everything worked fine, playing a
divx files used less that 5% CPU overall. No hardware has been
changes, only sw update.

I already "talked" to him...  He says, he can't reproduce the
behaviour, so I think, the problem is outside the driver.  As I said
above, the X-Server seems to (at least try to) use the hardware
acceleration.

After some searching, I think, this is the only one :-(
