Sure thing: I applied the patch on top of current coreboot-master and compiled the ROM using the "config-unreliable" from my initial posting.  Then I did a series of five warm reboots and watched the output on the serial console. Result: No more hangs! (Previously, it took like 20 attempts to get even one successful boot)

Great job, and many thanks!
