Goh lip & Tom,
Today a took the time to follow your advices and they finished without
errors.
A peculiar thing is:
sudo update-grub

Updating /boot/grub/menu.lst ... done
Well that looked good. However, bootinfoscript gave as important info:
....
Boot Info Summary:
=> Grub 0.97 is installed in the MBR of /dev/sda and looks on the same
drive in partition #1 for /boot/grub/stage2 and /boot/grub/menu.lst.
(info about boot sectors on /dev/sdb and /dev/sdc)
sda1:
_________________________________________________________________________
File system: ext3
Boot sector type: -
Boot sector info:
Operating System: Ubuntu 10.04.2 LTS
Boot files/dirs: /boot/grub/menu.lst /etc/fstab
....
(Info about other partitions on /dev/sda/ and on the other 2 drives)
...
A lot of partition info but I think irrelevant for the current problem.
If not I stand corrected. And then:
=========================== sda1/boot/grub/menu.lst:
I skip the standard comment and known info and then:

### END DEBIAN AUTOMAGIC KERNELS LIST
As you can see the kernels which sudo grub-update shows are not in the
file menu.lst and I have no idea where grub-update has stored them.
I also did update-initramfs -u but also no effect and my system boots
still with 2.6.32-25-generic instead of 2.6.32-32-generic.
The time stamp of menu.lst does not change. Is it an option to remove it
(i.e. to rename to .old)?
I hope I have given sufficient information for you to see what I have
overlooked.
