Just for the record, here's what I configured:

  <bootloader>
    <global>
	[..]
      <default>openSUSE 11.2 - Desktop</default>
    </global>
    <loader_type>grub</loader_type>
    <sections config:type="list">
       <image>(hd0,5)/vmlinuz</image>
       <initrd>(hd0,5)/initrd</initrd>
       <name>openSUSE 11.2 - Desktop</name>
       <original_name>linux</original_name>
       <type>image</type>
       <vgamode>0x314</vgamode>
       <configfile>1</configfile>
	[..]
    </sections>
  </bootloader>

and

  <scripts>
        <chroot-scripts config:type="list">
                <script>
                        <debug config:type="boolean">true</debug>
                        <chrooted config:type="boolean">true</chrooted>
                        <filename>0050_stage1_link_kernel_for_grub.sh</filename>
                        <source><![CDATA[#!/bin/sh
# The <bootloader>-section makes the kernel that is linked to /boot/vmlinuz the
# default. So we need to set that link correctly before the first reboot.
# Ugly, not fault-tolerant, but works good enough for testing.
echo 'Setting links for the newest desktop kernels:'
if [ -f "$(ls -tr /boot/vmlinuz*-desktop | tail -n1)" ]
then
        ln -sfv $(ls -tr /boot/vmlinuz*-desktop | tail -n1) /boot/vmlinuz
        ln -sfv $(ls -tr /boot/initrd*-desktop | tail -n1) /boot/initrd
else
        echo 'ERROR: Kein passender Kernel unter /boot/vmlinuz*-desktop gefunden.'
fi
]]></source>
                </script>
        </chroot-scripts>
  </scripts>

The script works fine, both according to its log and the resulting links.

On the finished installation, the /boot/grub/menu.lst ends up to boot not
/boot/vmlinuz, but rather /boot/vmlinuz-2.6.31.12-0.2-desktop and the name
differs from the one set in the bootloader-section as well. But as long as my
problem with stage2 using the wrong kernel is gone, I frankly don't care ;)
