No, this is not about Sun and IBM :) This is about MySQL. If you download latest 5.1.33 source code you may find there storage/ibmdb2i directory, which obviously is IBM DB2 related. Interesting that there is no mentioning of new engine in Announcement http://dev.mysql.com/doc/refman/5.1/en/news-5-1-33.html.
Quick look into source code says

PLAIN TEXT
CODE:
  1. MYSQL_STORAGE_ENGINE([ibmdb2i], [], [IBM DB2 for i Storage Engine],                                                               
  2.         [IBM DB2 for i Storage Engine], [max,max-no-ndb])                                                                         
  3. MYSQL_PLUGIN_DYNAMIC([ibmdb2i], [ha_ibmdb2i.la])

Also interesting that license of added files is not GPL, but

PLAIN TEXT

I think this is outcome of 2-year old press release
"MySQL AB and IBM Announce Open Source Database Support for the IBM System i Platform", it just took a bit a while to put it into source tree. I wonder what happened with policy not accept significant changes into production release.
