Actually, from this point of view, Grub2 is a step in the right 
direction: as opposed to Grub Legacy, it has an "os-prober" script 
which re-configures your boot menu, incorporating all the OSes on all 
your partitions it can find. So, it's not the "last installed" system 
that configures your boot menu as in Grub legacy, overriding any 
previous boot loaders. In Grub2 *you* get to choose which of your 
systems will configure your boot loader. Well, at least, that's the 
idea ;)

On an unrelated note, for those who are struggling in vain to make 
Grub2 boot graphics ("splashimages") work: the update-grub script in 
Lenny, for some reason or other, doesn't propagate the GRUB_GFXMODE 
variable from /etc/default/grub. That's why using the ${GRUB_GFXMODE} 
variable in  /etc/grub.d/00_header simply won't work. You have to set 
gfxmode literally, as in:

set gfxmode=1400x1050

The following (at least on my Lenny system) won't work:

set gfxmode=${GRUB_GFXMODE}

although you may have a perfectly defined GRUB_GFXMODE in /etc/default/
grub. In addition, not all jpeg images will work with Lenny's Grub2 (if 
you have such a problematic jpg, just convert it to png and it should
