I finally came across a solution, after several days.  It is very important 
that you don't edit it in the /boot/uEnv.txt of the beaglebone.  You need 
to change the uEnv.txt in the mounted partition.  For me it was as simple 
as connecting via USB to the host computer and just clicking on the mounted 
partition, editing the uEnv.txt file and rebooting.  I ended up deleting 
everything in uEnv.txt and just using this.

optargs=quiet capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN

Output looked like this.

 0: 54:PF--- 
 1: 55:PF--- 
 2: 56:PF--- 
 3: 57:PF--- 
 4: ff:P-O-L Bone-LT-eMMC-2G,00A0,Texas Instrument,BB-BONE-EMMC-2G
 5: ff:P-O-- Bone-Black-HDMI,00A0,Texas Instrument,BB-BONELT-HDMI
 6: ff:P-O-- Bone-Black-HDMIN,00A0,Texas Instrument,BB-BONELT-HDMIN
 7: ff:P-O-L Override Board Name,00A0,Override Manuf,bspm_P8_27_d

This then let me upload the new overlay called bspm_P8_27_d.

Thanks for your assistance Robert and hopefully someone find this useful in 
the future.  Hopefully everything looks good when I start writing some new 
code.
