Thanks for the detailed info, Sven. I did notice shortly after firing off that email that indeed the ofmap file is present for a 2.6.18 kernel, only not for that ancient 2.6.8 kernel I was looking at at first. This raises another question: It seems to me that this patch will fail for kernels that offers devspec in sysfs but does not ship with a modules.ofmap file. If so, applying this patch will cause yaird to stop working on older kernels that worked before.
