The chaining from grub-legacy menu to grub2 is just supposed to enable
testing of the grub2 install, it doesn't install anything. One has to
run "upgrade-from-grub-legacy" as root to finish the process, or simply
properly install grub2 in the mbr, and create the config.
If the boot process failed with the chainloading from grub-legacy, it
means that it would not have been a good idea to finish the process
anyway...

The package "os-prober" is taking care of other OS detection, it's
"recommended" but not automatically installed. I am using grub2 since
Lenny was testing, now on three squeeze, and three Ubuntu, no problem
here. Just got lucky maybe.
