The basic problem is that presence of a kernel package does not imply presence of the desired patch/enabled feature in that package, nor that the running kernel is the installed one. What you need to do is twofold: depend upon the presence of the ABI required, if you can get the kernel package maintainers to add an appropriate provides: entry, and secondly handle the absence of that ABI gracefully at runtime. -Rob -- GPG key available at: <http://www.robertcollins.net/keys.txt>.
