I sent a request in to Blackmagic as well as asking here.
I have the Master Collection 5.5.1 on a 2 x 2.26 Quad-Core Mac Pro with 12 GB of RAM running OS X 10.7.2.
I have the Decklink Studio 2 card that works with AE, Photoshop, and even when dragging a Sequence into the source monitor of Premiere.
But I can't get the Blackmagic Presets to load when selecting a new Seqence in Premiere. Blackmagic are the only presets missing.
Is this a Lion incompatibility?
I just ran the 5.5.2 update, uninstalled and re-installed the Blackmagic 8.6.1 Desktop Video package, and my Blackmagic Sequence Presets returned!
