My favourite way to combine pagination with infinite scrolling (for reading, at least) is to use columns - the line after the bottom of the first column is at the top of the second column, and scrolling down scrolls all columns along line by line. Scrolling left and right snaps to columns, and scrolling right by one column is equivalent to scrolling down by one page. Scrolling right by one page is equivalent to scrolling down by page_height (in lines) times page_width (in columns).
