OpenGL ES2 problems with Tegra hardware

Hello,

I’m using a TrimSlice mini computer that has the Tegra hardware in it. (Tegra 2 Ventana)
On the mini computer is Ubuntu 12.04 installed (armhf). The system uses the Kernel version 3.1.10. L4T is R16.3.

If I’m starting a program that uses OpenGL ES2 like glmark2, es2gears or my own application I get repeatedly this message on stderr:

Couldn't open /sys/bus/nvhost/devices/host1x/syncpt/22/max

This message seems to be generated from the Nvidia OpenGL libraries. I checked, this path is not available on my system. Did I forget to enable something in the config?
All started OpenGL programs have performance issues that I think are because of this missing /sys-path.

Hope that someone can give me a hint in the right direction.

Thanks
