Putting "dcon-freeze" at the top of boot.fth resulted the custom
logo being displayed nicely as in secure boot with no additional
tweaks required.  Thanks!

This is of secondary importance to me, but I still do not
understand why the Update.1 release candidate 703 fails to boot in 
secure mode.  I have even re-downloaded the image and re-flashed it
a second time.

Do I have to double check something in my mfg-data?  Both my laptops
are pre-MP.
