We have several EX90 with TC5.1.4 SW and register them successfully to CUCM 9.0.
We have a CUCM cluster, but the EX devices just learn the primary CUCM (yes, we know the stuff with Groups and Pools).
Has anyone been successful with registering EX to a CUCM Cluster with failover working?

You are correct, I know you know Groups and Pools
Unfortunately Secondary/Tertiary UCM nodes failover/fallback and SRST are not supported yet
Hopefully this will be coming in 2013.
No problem Martin
I dug up some link for you where this is mentioned:
