If you are running the 2.6.19 kernel, instead of loading the
mmc_block and sdhci modules, try loading the tifm_sd module. If you
get a message like "kernel: tifm_7xx1: sd card detected in socket 1"
in your logs when you insert a card, then running "modprobe



I had not used my SD slot for a while, and when I tried it with the
2.6.19 kernel, the way I used to access it no longer worked. I am
not sure what version of the kernel changed things. When I first got
it working, I had this in my /etc/rc.d/rc.local:

# Setup the 5 in 1 card reader for SD cards.
#
        setpci -s 04:06.2 4c.b=02
# Load the SD and MMC modules again.
        modprobe sdhci || exit 1
        modprobe mmc_block || exit 1

In order to get it to automount, I had to change a selinux mode.

semanage fcontext -a -t removable_device_t /dev/mmcblk.*

It doesn't look like it is needed any more...
