Many thanks for all the help received! Over the weekend I tried Gerry's 
detailed procedure, which went smoothly, except I still cannot boot 
Ubuntu. What did I miss? See details below, interspersed with Gerry's 
instructions.

===>All of the above went smoothly. I use the IBM boot manager and 
created a single one 200 GB primary partition for Ubuntu, besides 
another primary partition for eCS, along with a few logical partitions 
for use with eCS (maintenance, data storage, and work area).

===>o.k. (except Ubuntu proper does not offer a 64-bit version; Kubuntu 
and other flavors do. So I installed for now the Ubuntu 32-bit version.)

===>done, but the Ubuntu installer complained that I made no provision 
for the swap partition, which then could not be installed in that single 
200 GB partition I had set aside for Ubuntu. Obviously, in my next 
installation attempt, I need to use something like a 190 GB primary 
partition for Ubuntu proper and a 10 GB or so swap partition.) However, 
I am told that for the time being I could continue without a swap partition.

===>It did. However, after a reboot, I could only boot to eCS, not to 
Ubuntu. My attempts to somehow include the Ubuntu partition in the boot 
manager failed. How does one do that?

In short, basically, the whole procedure seems to work pretty much as 
intended, except that in the end, one cannot boot to Ubuntu; the eCS 
part worked fine. I think that perhaps Grub may need its own partition, 
which must be accessible to the IBM boot manager? Any help you may be 
able to suggest would be appreciated.
