Update.  I just followed the docs.  I had little idea of what I was
doing but I just did what it said.  Dang thing booted, first time.  Even
my fresh new kernel worked.  :-D :-D 

Since I was confused and thought /boot and efi could be the same
partition, I ended up with /boot on the root partition.  I may redo that
later.  It works tho.  Plus, loads of space for other images etc. 

I still don't understand the efi thing.  I'm booted up tho.  I'm happy. 
Now to get temp sensors and stuff to work.  I want to keep a eye on
temps for a bit.  I think the boot media was reporting the wrong info. 
Even the ambient temp was to high for this cool room.  It showed like
100F or something when my A/C is set to 68F or so.  Plus, the side is
off the case at times.  New battle.  ;-)
