Hi Nicolai, Patches look good I'll give them a whirl tomorrow when I have some free time. I'll have to dig out your headless piglit instructions since I still can't bring X up on my Raven board. Also I noticed the use of "(options.bitfields)" (etc, in print_waves) which is not your bug (since I did it first hehehe) but is a bug ... they should all be "asic->options.bitfields" which I'll fix in a follow-up patch after. (provided they apply and combined with the kernel patch doesn't oops on me I'll R-b + push them out tomorrow or Monday morning).
