Ah, thanks for clearing that up, I had assumed that not only ld but
also sdmmc itself was related to the SD card (I don't think I've ever
used SDIO devices, so I've so far only seen sdmmc in combination with
SD cards).

I forgot to mention this before - the previous output came from a
Raspberry Pi 3.  For a second positive data point, this is from a
Raspberry Pi 2 booting the exact same installation (i.e., removed SD
from Pi 3, plugged into Pi 2, powered on):

sdhost0 at obio0 intr 184: SD HOST controller
sdmmc0 at sdhost0
sdmmc0: SD card status: 4-bit, C4
ld0 at sdmmc0: <0x03:0x5344:SU04G:0x80:0x22d64220:0x10b>
ld0: 3781 MB, 1920 cyl, 64 head, 63 sec, 512 bytes/sect x 7744512 sectors
ld0: 4-bit width, High-Speed/SDR25, 50.000 MHz

As the Pi 3, it boots multiuser and I don't see any apparent issues
but I haven't done much else.

I haven't tried earmv6hf yet.
