Hi everybody,

I got a nice nifty notebook here (Dell Precision M4500, smolt profile at [0]),
which I'm trying to get the latest 'things' to work.
Almost all of the machine is in a working state (on openSUSE 11.3 even all out
of the box, exctept gfx) and this is highly impressive.

Unfortunately, at this time, the SD/MMC card reader seems not to work. In dmesg
output, I get those lines regarding mmc or sdhci:
dmesg | grep -e 'sdhci' -e 'mmc'
[ 9.769810] sr0: scsi3-mmc drive: 62x/62x writer dvd-ram cd/rw xa/form2 cdda
[ 9.819200] sdhci: Secure Digital Host Controller Interface driver

[ 9.970941] mmc0: Unknown controller version (2). You may experience

[ 1281.335537] mmc0: error -110 whilst initialising SD card

So the controller is seen / detected, the insertion of the card is seen as well
(last line), but just as it tells earlier, 'I do experience problems'
The card remains inaccessible of course.

Output of lspci -v for the SD host controller:

04:00.1 SD Host controller: Ricoh Co Ltd Device e822 (rev 03) (prog-if 01)
Subsystem: Dell Device 040c
Flags: bus master, fast devsel, latency 0, IRQ 19

Capabilities: [78] Power Management version 3
Capabilities: [80] Express Endpoint, MSI 00
Kernel driver in use: sdhci-pci

Is there anyway this can be worked on? Any pointers on getting started with it?
