So... on my c2d (1.8ghz) machine a reboot with initscripts takes about 40s.
With systemd it will either take (1) < 40s (2) > 40s. But probably the
deviation will not exceed ~5s.

Given that... why should I care about speed at all? Again your problem with
300 MHz kernel timer may be real, but is it relevant when talking about an
init system? Does it overweigh such pros as deprecation of ck and pm-utils, or
ability to lock a user in a cgroup?
