grub gets confused when I upgrade the kernel

[Hendrik Boom <hendrik@topoi.pooq.com>]

I have two different Debian systems on my EEEPC -- stable and testing.

Whenever testing installs a new kernel as a result of the routing update, 
my grub/menu.list file gets rewritten.  WHen it does this, it matches the 
kernels I have in one Debian sysstem with the fie-system root I have in 
the other.  I have to hand-edit menu.list to make things right again, 
using static boot stanzas in front of the AUTOMAGIC KERNEL LIST.

(a) Is there any way I can stop this misbehaviour? 

(b) If I were to progress to grub2, where I gather I can't take control 
of the boot process by editing menu.lst, is there some other way of 
making sure things go right?  I fear that one of these years, upgrading 
to grub2 will become inevitable.
