How about: CONFIG_SATA_PMP=y "SATA Port Multiplier support" under
>> Device Drivers > Serial ATA and Parallel ATA drivers (libata)
> And if that option is already enabled, try disabling it.

Thanks for the assistance. The PMP was enabled in the working kernel.  
In testing, I'm pretty sure I've had it both ways, without much effect.  
All the Intel and Via drivers were in place for SATA, AHCI, PATA, ATA 
and anything else I could think of.  Something I changed made /dev/sr0 
show up, and now I'm trying to figure out what it was.  So it's working, 
but I wish I had a better understanding of what was keeping it from 
working, and what enabled it to work.  If this weren't a live machine 
(my wife needs the router side of it for work), I'd play around more, 
but I'm just going to have to be content with the Damon Hardy solution 
(one of my co-workers who wrote on a customer ticket "Screwed around 
until it started working")  :-\
