FYI: I have a Lenovo X230 with Ubuntu 12.04. My card reader was not
working until I followed Premik's commands followed by rmmoding and
modprobing sdhci and sdhci_pci. As soon as I did that the card
automounted.
The following is from lspci -v.
02:00.0 System peripheral: Ricoh Co Ltd MMC/SD Host Controller (rev 07)
(prog-if 01)
Subsystem: Lenovo Device 21fa
Flags: bus master, fast devsel, latency 0, IRQ 16
Memory at f1d00000 (32-bit, non-prefetchable) [size=256]
Capabilities: <access denied>
Kernel driver in use: sdhci-pci
Kernel modules: sdhci-pci
I couldn't get the reader to work at all. It was giving me the
following in dmesg.
[15536.020115] mmcblk0: error -110 sending status command, retrying
[15536.020157] mmcblk0: error -110 sending status command, retrying

[15536.020202] end_request: I/O error, dev mmcblk0, sector 0
