This seems correct to me. I actually made similar changes some time
ago, but never got around to committing them. Make sure to get all
the NTP-related syscall vectors in the emulations, too.
Looks like ntpd(8) catches SIGSYS to deal with the case that the
kernel does not support those system calls, so the `side-effect'
you describe isn't going to cause any problems.
Go for it!
