Sigh...found it, after weeks of on-and-off work...  Our board has 64 MB of
RAM but I'm passing "mem=32M" to the kernel because we want our app to man-
age the high 32 MB.

U-Boot defaults to copying an initrd into the highest available RAM.  That
put it in an area outside of Linux's knowledge, D'OH.  All I had to do was
set U-Boot's 'initrd_high' env var and things work.

Thanks for the info anyway; I've saved it.
