Query to check CPU patch level

After moving from CPU patches to PSU patches for Database, we no longer get the CPU information from the query:

SQL> select comments from registry$history;

18 rows selected.

If you notice it only shows Patchset 11.2.0.2.5 instead of having two rows one for PSU and one for Jan 2012 CPU which is included in the PSU.

We always apply all CPU patches relevant to our techstack, which usually means the database patches applied with opatch and EBS patches applied with adpatch.  So I created a query based on the EBS patch numbers for CPUs from April 2011 - July 2012 CPU:

column BUG format a8;
column PATCH format a60;
set linesize 100;
set pagesize 200;
select b.bug_number BUG, b.LAST_UPDATE_DATE LDATE, decode(bug_number,
