Alexander, thanks for the quick response!

1. How can I tune the PCI configuration? With pciconf -w or so?
2. Unfortunately the sysctl did not change a thing with regard to the
Card reader.
3. I added the chip ID and the second device is now recognized as a
sdhci device but still does not see any card inserted:
