Yes you can.  Use vi or other plain-text editor to edit the
/boot/grub/menu.lst file.

As a bare minimum you could use these five lines:
1: title Old Ubuntu install
2: root (hd0,0)
3: kernel /boot/vmlinux-2.6.15-27-generic
4: root=/dev/XXX ro quiet splash
5: initrd /boot/initrd.img-2.6.15-27-generic

Notes:
Line 1 is purely to give Grub something to show in the menu.
Line 2 tells grub where the base hard drive is that /boot/ is located.
Lines 3 and 5 are the kernel and initial ram disk to load.
Line 4 are the boot options and tell the kernel which /dev/XXX device has
the root (/) filesystem.

>From your first e-mail you mentioned that Kubuntu was initially installed
on /dev/hda, so I'd use "/dev/hda1" for the root= line.  Or boot into the
new system and see if you can mount the /dev/hda# partitions to determine
what they held.

As for line 2, I believe that *normally* /dev/hda maps to hd0,0, and
/dev/hdb maps to hd1,0, but I could be mistaken.  Once you get lines 3-5
pretty well determined, you can play with editing the grub menu at boot
time to change the "root (hd0,0)" stanza.  When you find the right one,
change the file then.
