I don't know to accomplish exactly what you want, but I will give you two
pointers that you might find useful:

  + The `scroll-in-place' Emacs add-on package makes scrolling commends
    "effectively" undoable, in the sense that PageDown+PageUp will always
    bring the cursor back to its starting location.  Get this package from:

      http://www.cs.utah.edu/~eeide/emacs/scroll-in-place.el.gz

    The variable `scroll-preserve-screen-position', which is built into GNU
    Emacs, has a similar effect.

  + Often, you can get back to where you want to be by "popping the mark ring."
    The key binding for this is C-u C-SPC.  Read the online GNU Emacs manual
    for more information about "marks" and the mark ring.

Good luck! ---

Eric.
