Ah!  It didn't occur to me to run pciconf.  "pciconf -lv" shows this:

sdhci_pci0 at pci0:0:20:7:	class=0x080501 card=0x08651025 chip=0x78131022
rev=0x01 hdr=0x00
    vendor     = 'Advanced Micro Devices, Inc. [AMD]'
    device     = 'FCH SD Flash Controller'
    class      = base peripheral
    subclass   = SD host controller

So not only is it (apparently) recognized, but the sdhci_pci driver
attached to it!  But inserting or removing a card shows no activity.
What's my next step?                                      -- George
