Your config already looks like it *should* be passing control to the
boot sector of (hd1,0).

I have no experience with SATA or its drive naming/numbering scheme so I
wonder if Grub could be numbering things differently than you expect.
Can you double check the mappings in /boot/grub/device.map?  Also, at
the grub prompt, try typing "root (" and then using tap completion to
select the drive and partition; that might give you some clues about
what Grub thinks it's loading.
