I'm not sure what kdm is doing, as I have not taken a look at the source code.
However, I see the following in /var/log/kdm.log
GNU GRUB version 0.97 (640K lower / 3072K upper memory)
[ Minimal BASH-like line editing is supported. For
the first word, TAB lists possible command
completions. Anywhere else TAB lists the possible
completions of a device/filename. ]
grub> savedefault --default=5 --once
so I see that kdm seems to run grub, and not edit menu.lst or some other hack.

The grub and kdm maintainers are much more competent than I. However, I can
investigate more if no-one else is aware of the problem or cannot reproduce.
It's a bit time-consuming, so for the moment I am simply avoiding using this
feature - I'll stick to rebooting into linux :)
