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 :)
