There are a number of Kirkwood & Sheevaplug commits on the U-Boot tree, so I tried compiling[1] and running it, just to see what happened, with reserved hopes that maybe it would fix either my boot from USB[2] or SD[3] issues. When I rebooted, nothing appeared on the console what-so-ever.

I went back to my working U-Boot, but I thought it was an interesting experiment, and I'd be interested in any pointers about what may have gone wrong?
