Me again...

On another notebook with the same card reader I get a little further:

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
mmc0: detached
sdhci0: detached
sdhci0: <RICOH R5C822 SD> mem 0xd8002800-0xd80028ff irq 22 at device 9.2
on pci5
sdhci0: 1 slot(s) allocated
sdhci0: [ITHREAD]
sdhci0: detached
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
mmc0: detached
mmc0: <MMC/SD bus> on sdhci0

So the mmc device is detected everytime I insert a card and is removed
when I take the card out.
But I do not get a new disk device...

pciconf tells me pretty much the same like on the other notebook:
