You're probably using a newer version of resource-agents, I have 
resource-agents-1.0.3-2.el5 and:

# crm ra meta mysql|grep ^replica
# echo $?
# 1

I've found the patches for the MySQL RA though

http://hydra.azilian.net/gitweb/?p=linux-ha/.git;a=summary

And the original thread

http://www.mail-archive.com/linux-ha@lists.linux-ha.org/msg14992.html

The patches apply for a Master-Slave Replication setup, haven't tested 
them though.

So I guess there are 2 ways for a MS setup with MySQL.
