I'm currently doing some mods (and replacing the screen) on a HP Pavilion DV6-6135dx with an AMD A8-3500M APU. It has a "Blu-ray Player & SuperMulti DVD Burner" optical drive.
Your APU has the same 'UVD3' hardware acceleration as my model, so there is not a reason why it would not work (and the bezel properly align).
The service manual for the DV6-6135dx also says that only Intel models support SSDs. That would be wrong
The model number of the laptop is located in the battery bay.
