Sorry, here is the working patch (some line-number thing in the last one).

header_control.Height + item_size.Height;

                                } else
                                        v_scroll.LargeChange = v_scroll.Height;


Hmm, I can answer my own question about git bisect. It appears that the
questionable commit:

commit f571f51216d2138b8705aeb27a4ebe3aa88e28a2

        * ListView.cs: Properly adjust SmallChange and LargeChange values for
        our scrollbars depending on the view. Also, update the maximum allowed
        value when setting the values from SetScrollValue to use the already
        available information contained within them.
        Fixes the remaining bits of #543785.


    svn path=/trunk/mcs/; revision=156985
----------------------------

was only in trunk (which became 2.8) and never in 2.6 - and "git log 
mono-2-6-7..2.8 mcs/Managed.Windows.Forms" was misleading to only list 36
changes.
