You could try to variablize the values of the module parameters into
os-specific vars files and then do conditional include statements based on
the os.
So like
---
- hosts: all
gather_facts: yes
tasks:
- include: "{{ ansible_distribution }}-{{ ansible_distribution_version
}}.yml"
- name: set up serial console
replace:
dest: /etc/inittab
regexp: "{{ serial_regex }}"
replace: "{{ serial_replace"
notify:
- telinit_q
handlers:
- name: telinit_q
command: "/sbin/telinit q"
Where you would have files named like debian-7.yml, etc. And within those
files you would have serial_regex/replace defined along with any other vars.
Does that help?
