Both the squeeze and wheezy installers allow you to create a biosboot
partition. I think that it's called "Reserved ...".

It's too bad that parted calls it "bios_grub" (GNU publishes both grub
and parted...), gdisk calls it biosboot partition (as does kickstart),
and d-i calls it "Reserved ...". (I think that it's "Reserved BIOS
Boot Area" but I haven't seen this menu in a while.)
