Ah, and I was testing with i386, not x86_64, so that it explains that.

It's been quite a while since I've worked to add a new system call,
but my impressure is that in general the person who creates the new
system call needs to reach out to the architecture maintainers
(preferably with a patch :-), since otherwise the architecture
maintainers would have no idea that a new syscall has been added.
