I just tried this, and you're right, it doesn't hard lock the gpu. It will crash the entire system instead...

I also retested using my old 2.6.32.9 kernel, wich still hard locks the graphics. I also tested my current 2.6.32.13 kernel with drm from 2.6.33.4, which gave me a system crash.

Please note that I have a Radeon HD 2600 Pro. If you have a different GPU model you might have more luck than me...
