Hi,

Qt-embedded builds fine.
However running actual opengl ES2 code results in a segmentation fault.
Also qtdemo results in a segmentation fault.

I would like to give you more detailed information, however I'm a little 
short on time to work on this.
I will try to make a stacktrace tomorrow.

Regards,
Bastiaan de Nooij
