You can choose to publish open access conference papers through IEEE but you have to pay around $2000 (I forget if it was USD or AUD). I'm not sure about the exact costs for an open access Journal paper though. That said, IEEE don't prevent you from listing your own paper on your own website (in it's accepted form, not published form) provided you link the correct DOI and include the reference.

The ACM is similar, and I think (hope) they will eventually have to just open up all published papers by default. The main difference between the IEEE and the ACM to Elsevier is that the IEEE and ACM are professional organizations. They have a non-profit mission, whereas Elsevier is a for-profit company. I have no problem reviewing papers and serving on program committees when the organizing entity is a non-profit service organization. I think the the ACM and IEEE have a future in a fully open-access world, but Elsevier does not.
