thanks for sharing. I adopted your recipe, but turned the service into 
the task run by cron. RAM is precious resource on VPS.
I couldn't find a proper way to calculate times for cron, though. Also I 
think /etc/init.d/chef-client is not really necessary.

This what is have for now:

$ cat chef/recipes/client-deb.rb
case node[:platform]
when "ubuntu"
  if node[:platform_version].to_f >= 9.10
    service "chef-client" do
       provider Chef::Provider::Service::Upstart
       supports :restart => true, :reload => true
    end

    template "/etc/init/chef-client.conf" do
      source "upstart-chef-client.conf.erb"
      owner "root"
      group "root"
      mode 0644
      backup 0
      notifies :start, resources(:service => "chef-client")
      not_if do File.symlink?("/etc/init.d/chef-server") end
    end

    cron "chef-client" do
      minute ((0..59).to_a.delete_if {|x| x % 
(@node[:chef][:client_interval].to_i / 60) != 0 }.join ",")
      command "service chef-client start"
    end
  end
end

% cat chef/templates/default/upstart-chef-client.conf.erb
start on runlevel [2345]

task

script
        exec /usr/bin/env chef-client -c /etc/chef/client.rb -s <%= 
@node[:chef][:client_splay] %>
end script
