Hi there :)

I just wanted to report a bug (if it is) to you.
It happens on my up to date Ubuntu Lucid 64bit which is running on my laptop
(which is a lenovo ibm thinkpad T500 with intel graphics module i915)

When using the openscenegraph sample application shipped with the distributions
package, i encounter the following error:

osgshaderterrain 
Creating terrain...done.
Mesa 7.7.1-DEVEL implementation error: Unsupported opcode 79 (TEX) in vertex
shader
Please report at bugzilla.freedesktop.org
Warning: detected OpenGL error 'invalid value' after RenderBin::draw(,)
do_wait: drmWaitVBlank returned -1, IRQs don't seem to be working correctly.
Try adjusting the vblank_mode configuration parameter.


The do_wait line appears with every sample.
The programm does not crash, it just shows the "terrain" which would normally
have shaders applied, but which is now black and with flickering black bars in
z direction (so called "up")

I don't know if that will help you any further, but if you need more
information, here i am ;)
