Sorry Don, Shoot!
The root fs is on the SD card is how.
This may be your problem:

Yes, you are building a different kernel than the one on the card. I have
switched back and forth, looks like I went back to the old TS tree last week to
try and get as close to factory configuration as possible to push the parallel
port project through.
I know that if the kernel loads modules during boot from a different kernel
tree, there can be problems and if it is a different ABI, there will be
helltoupee.
Here is my kernel command line:
Kernel command line: root=/dev/ram0 rw init=/linuxrc lpj=498688 console=null
I had terrible luck with nfs root, it just wasn't stable. Our IT person bought
me a 100BaseT switch claiming that the auto-negotation of the host was Gigy and
this does not work well with a target at 100BaseT. My reaction to this was
"BS!", but the switch proved he was right somehow. Gave me the creeps.
