Thanks for trying to help.  Unfortunately, you don't have any suggestions 
that would work for me because they seem to require a higher level of 
technical knowledge than I have.  For example, "try lilo, then syslinux" 
was one suggestion, but I don't know how to do that, so I would have to 
spend a bunch of time finding out how to do it, then time doing it, then 
it probably won't work, or at least you don't seem to have any confidence 
in it.  At another point you give a long list of steps that I mostly don't 
understand such as "unpack the core tar.gz" -- which I get from where? -- 
and end with "all easy if the liveCD kernel supports your raid," but the 
Live CD does not work with the RAID, which is one of my problems.

But I really am grateful for your effort and you did give me a few ideas. 
One problem I've had though, is that when I google for solutions, I get a 
lot of what are essentially clues but without answers.

>From this list I did get one off-list reply that seems like a really good 
lead.  The person claimed that I need to create a /boot partition with ee 
type and that I can use GPTfdisk.  Apparently, GPTfdisk is in the Ubuntu 
package gdisk.  So maybe I can go back to the old RAID1 instructions that 
B-o-B and I put together and just use GPTfdisk instead of fdisk, but with 
a /boot partition of maybe 10MB, and then Ubuntu will install GRUB 
automatically.  I'm going to guess it will work.  I'll let you all know.

Also, if that works, it would probably mean that I could have done my 
installation back in October even more easily if I had only made a /boot 
partition of the right type (ee).  I've been going without the /boot 
partition and just using /.
