Follow-up Comment #1, bug #26834 (project grub):

by adding:

set debug=all
set pager=1

at the grub prompt, I could see a little bit of what was going on.

(hd0), the disk that is larger than what the BIOS can see gets opened
successfully and its partition table gets read, however, there is an error:

disk.c 396 Read out of range sector 0xffeb

and then reading (hd0,1) fails.

I believe that something in the "Read out of range" causes reading (hd0,1),
even though if I remove the "search" line from the grub menu entry so that
(hd0,1) is read without trying to read an "out of range sector", the read of
(hd0,1) is successful and I can boot from the large hard disk.
