Two GRUB setup can boot one each of two installs, but not the other, why

Hi, 

I have a very strange GRUB problem.
My system has two disk drives, one of which with two Linux installs.
MBR of each disk has been setup from separate installs to allow booting
either Linux:

IDE disk (MBR setup from IDE part2)
Part1: Mint 7 (Ubuntu 9.04 based)
Part2: Ubuntu 8.04

SATA disk (MBR setup from IDE part1)
Part1-5: swap and user-data partitions

Grub version of both Linux installs is 0.97.

I have identical pair of stanzas for these two Linux installs in both
partitions' /boot/grub/menu.lst:

title           Linux Mint 7 Gloria KDE, kernel 2.6.28-11-generic
#root           (hd1,0)
uuid            3403d691-06fd-4646-840c-8f936fd99ab9
#kernel         /boot/vmlinuz-2.6.28-11-generic root=/dev/sdb1 ro quiet
splash 
kernel          /boot/vmlinuz-2.6.28-11-generic
root=UUID=3403d691-06fd-4646-840c-8f936fd99ab9 ro quiet splash 
initrd          /boot/initrd.img-2.6.28-11-generic

title           Ubuntu 8.04.1, kernel 2.6.24-24-generic (on /dev/sdb2)
#root           (hd1,1)
uuid            9c17f912-7f27-40c4-a8c2-141924762217
kernel          /boot/vmlinuz-2.6.24-24-generic
root=UUID=9c17f912-7f27-40c4-a8c2-141924762217 ro quiet splash 
initrd          /boot/initrd.img-2.6.24-24-generic

I  stress again that pair of stanzas in question are copies of each other. I
have confirmed this by diffing them.

I can boot both Linux installs from the MBR that was setup by that very
install. No problems.
However, neither of them can boot the other install. I get "Error 15: file
not found." 

In other words, I *can* boot from IDE disk's MBR the Ubuntu 8.04 install,
but *cannot* boot the Mint install. Opposite is also true, i.e. I *can* boot
from SATA disk's MBR the Mint install, but *cannot* boot the Ubuntu install.

Since the stanzas are the same, files is really where they should be, and
the error message is bogus. As each stanza works from one MBR, but somehow
the same stanza does not work from the other MBR. 

I am totally stumped.

So, to switch between these two Linuxes, I am forced to change boot order
from BIOS
everytime. Pain in you know where. :-(

I know it should not be necessary but, I even re-setup the SATA MBR after I
added the Ubuntu 8.04 stanza. Needless to say it did not help.

What am I missing?

Thanks in advance.
