This is part of the problem.  I have tried pressing ESC when grub
starts, even trying rapid-fire ESC-pressing during the boot.  But Grub,
stops immediately, displaying the "Error 15", almost as if it can't find
menu.lst, although I don't know if this is what is causing the problem.
During my most recent installation attempt, I opened a shell right
before the reboot to look at menu.lst, which I found
in /target/boot/grub/menu.lst.  The kernel references all pointed
to /vmlinuz... rather than /boot/vmlinuz..., so I changed the
references, prepending "/boot".  Sadly, the result was the same.

Could there be any conflict with having had LILO installed prior to
Grub?  Looking at the installation logs, it appears that Grub installs
correctly, so I don't know what could be the problem.  

I would really like to turn on verbose mode in Grub, but I'm not sure
how to tell the Ubuntu installation to do that.
