the problem was (is?) that when the update took care, it asked me if I wanted to keep my menu list or put the maintener's version. I took the maintener's version and it wrote the above menu.lst and of course without the initrd line it failed to reboot.
It is not a problem for me as I know my way around but if you release this update (I believe it came from hardy-proposed) as is, there will be a major poopoo if suddenly nobody can boot. It happened when I updated the following.
