Unhappy Re: Nvidia support for Xen

I tried to install nvidia driver on opensuse 11.4 as described by user moenchmeyer in this forum.
Unfortunately it doesnīt work. Iīm able to compile the driver with standard kernel as well as xen kernel.
With the standard kernel the desktop effects in KDE work beautifully - with xen kwin tells me, that the desktop effects were disabled because compositing is to slow..

log entries form standard and xen kernel are the same when nvidia driver is loaded:
[17754.047605] nvidia 0000:01:00.0: PCI INT A disabled
[17765.372650] nvidia 0000:01:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
[17765.372662] nvidia 0000:01:00.0: setting latency timer to 64
[17765.372667] vgaarb: device changed decodes: PCI:0000:01:00.0,olddecodes=none,decodes=nonewns =io+mem
[17765.372854] NVRM: loading NVIDIA UNIX x86_64 Kernel Module 270.41.06 Mon Apr 18 14:53:56 PDT 2011

The Xorg.0.log are identical for both kernels.

I tried to play around with several options in xorg.conf:

Section "Screen"
Option "RenderAccel" "True"
Option "AllowGLXWithComposite" "True"
Option "AddARGBGLXVisuals" "True"
Option "DamageEvents" "True"
Option "TwinView" "0"
Option "UseEvents" "false"
Option "TripleBuffer" "1"
Option "BackingStore" "1"
Option "PixmapCacheSize" "70000"
Option "OnDemandVBlankInterrupts" "true"

None of these options are necessary to make desktop effects work with the standard kernel. With xen nothing helped.

The only "alarming" message I could find is in .xsession-errors :

OpenGL vendor string: NVIDIA Corporation

kwin(10858): Invalid framebuffer status: "GL_FRAMEBUFFER_UNSUPPORTED"

Dr. Google doesnīt give any help on "GL_FRAMEBUFFER_UNSUPPORTED". I donīt even know, if this message is the cause of my problem.

This is driving me nuts.... help!!!
