Hi
I'm trying to enable GPU on my custom kernel. I have applied a patch from Nick's repository, But when I allow `gpu` node in the Transpeed device tree, the kernel freezes here:

When I disable the `gpu` node. The Xserver comes up. However, the videos are playing slowly and the CPU usage is 100%.
Any idea what could be the problem?
