No, just I don't think that situation can happen. Maybe the problem is just 
that glibc is built against 2.6(i.e. you should try not only replacing 
headers, but also rebuilding glibc after that). Maybe this could be related 
with new things from glibc and 2.6, i.e. vsyscall or NPTL(I am just shooting 
in the middle, I don't even have ideas of what vsyscall is).

I've tried even if any of the header-generator programs use some changed 
headers, but for I saw is that every definition stayed the same
(except
#define PTRACE_OLDSETOPTIONS         21
which had same number but was named PTRACE_SETOPTIONS in 2.4).

I understood this; only I think this doesn't happen...
