UPDATE: There is some strange lag while copping files from or to the SD card!
I recently reinstalled my laptop (Acer Extensa 5620z) with OpenSUSE 11.4. Everything worked out of the box, (which is impressive) except the card reader.
If you look at /var/log/messages when you insert a card, you will see something like this:
tifm_core: MMC/SD card detected in socket 0:1
It means that the kernel has detected your card but it don’t think it’s memory card or storage device. Here the setpci command comes handy.
NOTE: You need to be root in order to preform the steps required
1. List your devices with lspci and find your card reader entry:
0f:06.2 Mass storage controller: Texas Instruments 5-in-1 Multimedia Card Reader (SD/MMC/MS/MS PRO/xD)
Notice the first colum 0f:06.2. This is your device ID, you will need it later.
2. Execute the following command:
Replace 0f:06.2 with your device ID!
setpci -s 0f:06.2 4c.b=0x02
Your card reader should work now. In order to make this change permanent, you may place the command from step 2 in /etc/rc.d/after.local.
