SubjectSyscall trouble

Hi all!

I have implemented a systemcall against linux-2.6.8.1 using the following
patches:

This works like a charm. If i apply this to linux-2.6.9 it does not work
anymore. The syscall is in kallsyms, but nothing happens when I call it.


Any suggestions?

What am I missing?
