This bug has been fixed in hardy, in grub version 0.97-29ubuntu7 and above:
grub (0.97-29ubuntu7) hardy; urgency=low
* debian/update-grub: use ucf to record changes to the autogenerated
kernel list
It is still advisable that boot options for other operating systems such as Windows be added outside the "automagic kernels list" markers, but going forward users will receive a debconf warning from update-grub if the update will overwrite local changes.
