If this looks good I'll go ahead and clean it up for the other arches and OSes.
Hi Kumar,
Thanks to your sequence hint, interrupt command hint, and one additional piece, I have this working now.
The missing piece is reserving memory for the stack before copying the ramdisk to high mem. It looks like this was lost when you consolidated the machine-specific lib_*/bootm.c do_bootm_linux() functions into one. Without the reservation code, the copy overwrites the stack. Seriously bad karma.
See below for a proof-of-concept hack.
I think my solution is a bit cleaner for us (adding arch_lmb_reserve). Take a look and see how that works for you.

Oh yes, my hack was just to verify that reserving the stack space solved my problem. It was not a solution.
Thanks, gvb
