It may be that clock parameters or something similar are not properly configured (I don't have any datasheets for these devices). There can also be a mechanical failure of the SD socket (these things do happen). Can you confirm that the socket and media are good, by trying them out under windows or something? Additional approach you can follow is to try and enable SDHCI interface if it's available on your chip (xx21 have it and can be made to use it) and then try it with sdhci.ko driver. If you want to experiment with sdhci (a tricky exercise), some information is available here: http://www.gentoo-wiki.info/Acer_Ferrari_4005WLMi#SDHCI
