The problem persists with kernel-source-2.6.10-4 and nvidia-kernel-source 1.0.6629.
The same problem with choppy 2D video (and then also audio).
Moreover this time I had to manually run depmod after installing the kernel (nvidia.ko has not been visible).
Moreover, sometimes when starting xdm the card died with debug output as in the following two listings (first with AGPGART, second with NVRM).
I guess I will stay with 2.4.x for some longer.
Thank you for your support, Mikolaj
