Okay, that explains a few things. The u-boot binary also sounds a bit
dangerous, because the NAND partitions have changed recently. So if
you mix instructions for the old layout with a new u-boot, this ought
to add a few plot twists before the happy ending.

What surprises me is that the Debian-style bricking appears to kill
u-boot itself, which means that one then has to fiddle with the USB
boot contact. If u-boot was still at least operational (even if
there's nothing for it to boot or if the rest of the system is at the
wrong places), one could enter USB boot mode simply by holding the
[U] button when the system comes out of reset.
