Does it mean , that a proper NVIDIA driver is just not available for the
most recent
2.6.29-rc5 ?

Are you using the nvidia binary driver? I would be surprised if it worked out of the box; if changes need to be made to the binary parts, it may not
be fixable at all.


I believe the current driver works with Xen because somebody outside
of nvidia contributed a patch, I use the nvidia binary driver with Xen
3.2.1 and my custom dom0 kernel which is patched with
openSUSE Xen patches rebased to apply to vanilla, it works very well
but when pv_ops is merged into mainline the nvidia driver will
probably work when it is running on the bare metal but not under Xen

Having said that the patch for Xen support only touched the open
source parts of the driver, as soon as the current problems with hvm
on pv_ops are fixed I will be testing pv_ops and nvidia driver and I
will attempt to fix any problems, my C skills are improving so I might
be able to figure it out.

Did you ever figure this out? I've just hit the same problem. It looks like the source code part of the Nvidia kernel module has the code necessary to work on an old Xen Linux, but if it detects CONFIG_PARAVIRT set for a pv_ops kernel, it gives up an doesn't attempt to work with Xen at all.
