Paraphrasing from the cron cookbook and extrapolating a bit:

case node['platform']
when "redhat", "centos", "scientific", "fedora", "amazon"
  svc = "crond"
when "debian", "ubuntu", "suse"
  svc = "cron"
end

service 'cron' do
  service_name svc
  supports [ :reload, :status ]
  action :reload
end

template "/etc/cron.d/blah-maint" do
  source "blah-maint-cron.erb"
  mode 0644
  notifies :reload, "service[cron]"
end

If you can just agree to call the cron service cron, you can set the
actual service_name that chef will use based on the platform driven
variable and no one else has to care.
