you can set the style property GtkComboBox::appears-as-list, but that  
doesn't work quite right in gtk+ 2.4.x...  the popup window doesn't  
have a scrolledwindow in it, so when the list is long, it's unusable.   
there's gtk+ bug logged about this:
http://bugzilla.gnome.org/show_bug.cgi?id=135543

gtk+ shows more recent activity on this than bugzilla:
http://cvs.gnome.org/viewcvs/gtk%2B/gtk/gtkcombobox.c? 
rev=1.102&view=markup


if you build gtk+ out of cvs (e.g. with jhbuild) then this code works:

  use strict;
  use Gtk2 -init;
  my $window = Gtk2::Window->new;
  my $model = Gtk2::ListStore->new ('Glib::String');
  foreach (0..50) {
      $model->set ($model->append, 0, "thing $_");
  }
  my $cb = Gtk2::ComboBoxEntry->new ($model, 0);
  $cb->set_name ('little-jerry-seinfeld');
  Gtk2::Rc->parse_string ('
  style "my-style" { GtkComboBox::appears-as-list = 1 }
  widget "*.little-jerry-seinfeld" style "my-style"
  ');
  $window->add ($cb);
  $window->show_all;
  $window->signal_connect (destroy => sub {Gtk2->main_quit});
  Gtk2->main;
