(Get the code!)
Ah now that's weird: it works when I boot with an SD card inserted (rebooted into windows to check: the reader appears as 4 PCIe devices for each standard it supports)
lspci now lists:
07:00.0 System peripheral: JMicron Technology Corp. SD/MMC Host Controller (rev 30)
07:00.2 SD Host controller: JMicron Technology Corp. Standard SD Host Controller (rev 30)
07:00.3 System peripheral: JMicron Technology Corp. MS Host Controller (rev 30)
07:00.4 System peripheral: JMicron Technology Corp. xD Host Controller (rev 30)
new dmesg messages:

now I can eject and insert cards, everything works.
But when no card is inserted during boot, the PCI devices don't even exist… (is there maybe a PCI rescan-option to set somewhere?)
