missing enterprise MIB?

Working on setting up custom mib polling for IBM RSA adapters.   

The IBM README indicated it should be 1.3.6.1.4.1.2.3.51.1

Orion only has 1.3.6.1.4.1.2.3.51.2  -  that OID is for their bladecenter management adapter, not the RSA adapters.  By the way, that OID using custom MIB polling works on my bladecenter.  :-)
