Debian squeeze/sid is dilivering GRUB 2 if you check the grub package information.
You can manually install the package grub-pc
Then install package os-prober, not sure why it is not listed as grub-pc's dependencies.
Run the following command to detect other OS on the same host.
Reboot and you'll see the chainload into GRUB 2 and run upgrade-from-grub-legacy note.
We'll see GRUB is still at 1.96;-)
BTW: Ubuntu and other mainstream distros are going to push GRUB2 in their next release. Rolling releases like Arch and Gentoo, already there as option;-)
