After setting hw.sdhci.debug=1 and hw.mmc.debug=1 in /etc/sysctl.conf
and doing a verbose boot, then inserting and removing an SD card, all
I get in "dmesg | egrep mmc\|sdhci" is:
sdhci_pci0: <Generic SD HCI> mem 0xf0c6c000-0xf0c6c0ff irq 16 at device

(Same for "egrep mmc\|sdhci /var/log/messages".)
"pciconf -lv" suggests this is a:

vendor = 'Advanced Micro Devices, Inc. [AMD]'
device = 'FCH SD Flash Controller'
class = base peripheral
subclass = SD host controller
Are there some quirks I should define for this controller? -- George
