Looking at your original question here are a few for you:

1. is the boot still on hda?  if so then you will need to ensure that
you edit the /boot/grub/grub.conf there.

2. have you installed linux before on the disk that you are using for
hdb?  If so and you user using the BIOS to boot to the secondary hard
drive on the Primary channel (hdb) then you will need to ensure that
you run grub-install /dev/hdb

3. what is your fstab setup as and what is the label on hdb?  that may
be causing some issues.


I would be inclined to think that you will need to get grub configured
by chrooting in to the hdb then doing grub-install

Could  you list the partition information (ie hda1 = /boot, hdb1 = /) fully?   

Looking at your grub.conf the question that I have is that have you
run grub-install? and is so how (ie using what parameters?)

Where is the boot that you are trying to boot to right now?  is hda
the only active partition?

Worst case bring it to the installfest on the 18th (if you can) and I
will give you a hand bailing it out..
