Simple, edit /boot/grub/grub.conf
Enter something like the following. You'll have to enter the correct
kernel and initrd filenames for Red Hat and SUSE. These files are in
/boot.

default=0
timeout=20
splashimage=(hd0,1)/boot/grub/splash.xpm.gz
title Red Hat Linux
        root (hd0,1)
        kernel /boot/vmlinuz-2.4.18 ro root=LABEL=/
        initrd /boot/initrd-2.4.18.img
title SUSE Linux
        root (hd1,0)
        kernel /boot/vmlinuz-2.4.12 ro root=LABEL=/
        initrd /boot/initrd-2.4.12.img
title Windows XP
        rootnoverify (hd1,1)
        chainloader +1

I think the WinXP will work, its an adaption of my Win98 script. Also,
this assumes that Redhat Linux is in the second partition, SUSE is in the
first partition and XP is in the second partition. If you have any swap
partitions before them, you'll have to increment the second number in
(hd0,1) and similar partition references.
Read thru the "info grub" documentation. Grub's easy and because you can
fiddle with it right from the boot loader level, you can change your
settings almost real-time until you get what you want.
