If you have a S105 with the PCIxx12 instead of the PCIxx21, then you
would get something like:

04:06.2 Mass storage controller: Texas Instruments Unknown device 803b
I have to try out just using the 4c.b=02, as I am using something a
bit more complicated, but for the PCIxx12, that would be

setpci -s 04:06.2 4c.b=02

Note that it is one subdevice lower then the PCIxx21.

xx:xx.0	Cardbus bridge
xx:xx.1 Firewire
xx:xx.2 MM card reader
xx:xx.3 SD card reader

Here is the script I use.

#!/bin/bash
#
# Script to enable SD interface of the TI PCXxx12 interface.
#

# Remove SDHCI and MMC modules, if they are installed.
        modprobe -r sdhci
        modprobe -r mmc_block
# Change what interface is enabled.
        setpci -s 04:06.3 86.b=90
        setpci -s 04:06.2 4c.b=02 # FlashMedia SD disable
        setpci -s 04:06.3 04.b=06 # SDHCI Mem+ BusMaster+
        setpci -s 04:06.3 88.b=01 # SDHCI DMA enable
# Load the SD and MMC modules again.
        modprobe sdhci || exit 1
        modprobe mmc_block || exit 1
        exit 0
