Dual boot with Two HDDs using GRUB?

I thought I understood GRUB but this has got me puzzled.

If I have two HDDs:
hd0 = XP
hd1,0 = Vista
hd1,1 = Arch (I installed GRUB to this partition as well)

and I want to use NTLDR to chainload GRUB, how do I do it if NTLDR is on (hd0,0)?

On a normal (single HDD) dual boot setup it is quite easy: install the GRUB files to (hd0,1), dd the first 512 bytes in /dev/hda2 and copy it to hda1, then edit the boot.ini file in hda1 to load the dd image saved there.

However, when NTLDR is on (hd0,0) and the GRUB stage1.5 and stage2 files are on (hd1,1) how can I achieve a dual boot system using NTLDR to chainload GRUB?  Can GRUB stage1 load from (hd0,0) and look for stage1.5/stage2 on a completely separate hard drive (hd1,1)?  Or can't it be done?

As I said, it's got me beat.  Has anyone achieved this?
