Detecting systems booting with GRUB2 in anaconda

I was asked about problem with installing Fedora 13 on a machine
that is dual booting Windows 7 and another distro using GRUB2.

There is nothing about GRUB2 in Installation Guide
"To add, remove, or change the detected operating system settings, use the options provided."

It is not clear is anaconda capable to detect properly such distro
that uses GRUB2 and add it as additional system to Fedora GRUB menu list?

Here is e-mail  that I received about this problem:

> And Fedora has made my ubuntu installation unreachable (remember I'm a
> novice). I expected GRUB2 like behavior - list the available OSes.
> Instead I have Fedora and Other, with other pointing to Windows 7.

> > You can try to add Ubuntu to this grub.conf
> Unfortunately, it looks like I was nailed pretty good on this one.
