That part I think (thats probably a bad thing) that because I didn't have 
SIMPLE_TUNER enabled, which I see is but its not working in this old boot 
either, but its at least seen, but there is no evidence that 
/lib/firmware/dvb-fe-or51132-vsb.fw is being loaded even in this old boot.

The instructions are ambiguous at best in the make xconfig help screen:

Oren OR51132 based (DVB_OR51132)

CONFIG_DVB_OR51132:

An ATSC 8VSB and QAM64/256 tuner module. Say Y when you want
to support this frontend.

This driver needs external firmware. Please use the commands
"<kerneldir>/Documentation/dvb/get_dvb_firmware or51132_vsb" and/or
"<kerneldir>/Documentation/dvb/get_dvb_firmware or51132_qam" to
download firmwares for 8VSB and QAM64/256, respectively. Copy them to
/usr/lib/hotplug/firmware or /lib/firmware (depending on
configuration of firmware hotplug).

Symbol: DVB_OR51132 [=m]
Type : tristate
Prompt: Oren OR51132 based
-------------------
That file looks like the download and strip script to put those 2 files
into /lib/firmware, and both of those firmwares are present in 
/lib/firmware, but how they actually get loaded is _not_ at all clear.

There is in this machine, a /usr/lib/hotplug/firmware tree also, were these 
files miss-placed?  I can put copies both places I guess.  Actually, they 
were simlinks, and that was missing, so I made one.  Reboot again after 
adding simple_tuner.

Thanks Mike, Ilia.

Cheers, Gene
