Update: The lpfc driver shipped with RHEL 5.3 will work with the Emulex LPe1205-M
Details:
According to RedHat, the lpfc driver shipped with RHEL5 U3 is: 8.2.0.33.3p. The Emulex site for the LPe1205-M links to a Linux kernel drivers section which links to SuSE's lpfc download site and EMC Manual describing the lpfc. According to another Emulex site, the 8.2.x.x driver supports the LPe12xx and LPe1200x series adapters. They also go so far as to list Red Hat 5.2 (which ships with 8.2.0.22) as a distro which "include[s] a driver on the installation media supporting the LPe12xx and LPe1200x series adapters.
Update 2: A stock kernel from RHEL5.3 is working with the Emulex LPe1205-M. The correct module was loaded automatically and I'm able to see my LUNs:
