Dan,
First let me thank you for still being around to
answer questions for people like me. You helped me out
a lot a few years ago when I was just starting to work
on all the embedded stuff. I am glad you are still
helping everyone else.

I will try the zImage trick but I just wanted to know
if the assumption here is that the kernel already
understands the EEPROM data format to construct
bd_info. Is that correct? If the kernel is unable to
get to this data, is there another way to pass this
info to the kernel?

Thanks much.
