I updated to HEAD and opted for the second suggestion as it seemed less
disruptive to the u-boot arrangement (I'm not quite ready to poke it
that hard).  The result was:

[...]

Another interesting thing in the dmesg was:

[...]
sdmmc0: couldn't supply bus power
sdmmc0: couldn't enable card: 22
[...]

I changed hosts since the last time, so perhaps the power management IC
thinks it doesn't have enough power.  The stock linux operates properly,
however.  For some reason, the ethernet PHY wasn't initialized properly
on power-up and it couldn't see the network until I pressed the RESET
switch.
