Much better! Loading mmcsd first, then mmc and sdhci gives me the mmcsd0
device:

sdhci0: <RICOH R5C822 SD> mem 0xd8002800-0xd80028ff irq 22 at device 9.2
on pci5
sdhci0: 1 slot(s) allocated
sdhci0: [ITHREAD]
mmc0: <MMC/SD bus> on sdhci0
mmcsd0: 1924MB <SD Memory Card> at mmc0 16MHz/4bit

But I still cannot use it:
lars@pts/3 # ls -l /dev/mmcsd0*
crw-r-----  1 root  operator    0, 120 Nov  6 19:36 /dev/mmcsd0
crw-r-----  1 root  operator    0, 121 Nov  6 19:36 /dev/mmcsd0s1

lars@pts/3 # fdisk /dev/mmcsd0
fdisk: could not detect sector size


lars@pts/3 # mount -t msdosfs /dev/mmcsd0s1 /mnt
mount_msdosfs: /dev/mmcsd0s1: : Input/output error


What am I missing?
