Which kernel version are you referring to? 2.6.14.3 lacks that file. I see that 2.6.16 is right around the corner. I would really appreciate it if you could have a look at this. I have very little experience in kernel hacking. Last time I wrote something nontrivial was about 8 years ago. If you're not interested, I can try to come up with a cx88-specific patch, which can be refactored later. Marko
