I believe that you can do this with layers. On the main, set the background-attachment property to scroll. Overlay this with a <div> block that is anchored at whatever point that will contain the things that you want to remain still.
If this doesn't work exactly, overlay the page first with a div with a scrolling background and then place a <div> with no scrolling or only overflow scrolling under it (so it's not inheriting anything) and put you text in this second <div> block. also make sure the second div has no background or it will cover the first.
