Do you mean this specific commit:
http://git.kernel.org/?p=linux/kernel/git/tiwai/sound-2.6.git;a=commit;h=3af9ee6b83c4c3f2577719e31e7d2af1ce996557 
?
The thing is that I only know how to build a kernel using Fedora RPM and 
I have never built it purely from source. As a result, I can easily test 
patches but testing whole trees might be tricky. If it is a problem, I 
can try to seek help how to create RPM out of your tree. I'll try to 
test it one way or the other once I get back home in the evening (I'm in 
CEST time zone).
Thank you for all the input so far.

Julian
