It may be hidden. You do have a different version of the chipset then I do. You may find the information at http://mmc.drzeus.cx/wiki/Controllers/TexasInstruments/FlashMedia helpful. I think you may have to use the setpci command to turn on the SD interface. You can try running setpci -s 01:06.3 4c=0x22 and seeing if that works for you. You may have to unload and reload the mmc_block and sdhci modules for it to work. Mikkel -- Do not meddle in the affairs of dragons, for thou art crunchy and taste good with Ketchup!
