How about adding an entry in grub.conf that is similar
to how we boot windows from grub:

title Ubuntu-9.04
         rootnoverify (hd0,0)
         chainloader +1

I do not know which disk/partition your ubuntu is on,
so you have to adjust (hd0,0) accordingly.

This will work, if you installed ubuntu's bootloader on it's partition.
