Dell Inspiron 910 (Mini 9) and SDHC memory cards

Yesterday I got my Mini 9 and I am very delighted. Unfortunately the technical informations from Dell about this netbook are incomplete. I cannot find any information about the cardreader. As the built in SSD has only 16 GB, I like to extend the memory with a 8 or 16 GB SDHC. But first I must get the information, if it will work.
