With 10.1 in rescue mode when I do the chroot, it says that /dev/hda
no longer exists. ie. even fdisk -l /dev/hda fails.

My assumption is that with 9.2, 10.0, 10.1 /dev is dynamic and built
during the boot process.  So when I chroot I basically lose the
ability to see my drive.

I've got SUSE 9.2 booted into rescue mode right now.  With it I tried
the chroot approach and I get:
# grub-install /dev/hda7
/dev/hda7 does not exist or is not a block device.
# grub
> root (hd0,7)
Selected device does not exist (IIRC, its in another room)

FYI: I also tried to boot 8.2 to rescue mode, but it does not display
on the flat-screen monitor I currently have attached.
