Okay, sectionnext seems to work, thanks for the hint. However, the problems 
are now:

1) If I start with the top node, it doesn't have any useful keys set, except 
NodeNext, which appears to point to the first section, fine. Unfortunately, 
that node for the very first node does not have any @'section_childs' set 
(since apparently it comes from a @node and not a @chapter)...
My code to obtain the top node is:
    # Get the top node:
    while ( defined($current_element->{'sectionup'}) and
                 ($current_element->{'sectionup'} ne $current_element))
    {
        $current_element = $current_element->{'sectionup'};
    }
    # Now loop through all top-level chapters, unfortunately, the top
    # node does not have a section_childs key, so I have to use NodeNext
    $current_element = $current_element->{'NodeNext'};
    while (defined($current_element)) {
        push (@toc_entries, generate_ly_toc_entries($current_element, ...));
        $current_element = $current_element->{'sectionnext'};
    }

The first chapter (the one obtained with NodeNext) does not have any 
section_childs and also does not describe the chapter, but the @node before 
it... All following chapters have section_childs and work just fine. See e.g.
http://kainhofer.com/~lilypond/texi2html-out/Divisi-lyrics.html

2) The indices seem to be split up into multiple chapters, cluttering the TOC 
with lots of entries at the end, which I don't want printed at all (and which 
are not printed in texi2html's TOC). Apparently, these index pages are 
included with sectionnext...

Cheers,
Reinhold
