Under Linux it probably shows up something like this:

The chip has 4 functions in one PCI slot as far as the system is
concerned. To make it work, I had to run a script. I added it to
/etc/rc.d/rc.local.
#!/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 04:06.2 4c.b=02
# Load the SD and MMC modules again.
modprobe sdhci || exit 1
modprobe mmc_block || exit 1
exit 0
What it does is turn off the MMC controller and turn on the SD
controller on the chip. I guess they can not both be on at the same
time. I am not sure what happens if you insert a MMC or a Memory
Stick after doing this, as I only have SD cards. (Well, I have
Compact Flash and Smart Media cards, but they do not fit...)
If your laptop has the chip mapped to a different PCI bus them mine
does, you will have to adjust the setpci command to match. It is bus
4, slot 6 on my Toshiba. (04:06.x)
