I tried to use this particular card to run Debian as described at
http://www.cyrius.com/debian/kirkwood/sheevaplug/unpack.htmlwith no luck.
Boot stops with `Bad Magic Number' message:
SDHC found. Card desciption is:

Bad Magic Number
Debian runs w/o problems on Patriot 6 class SDHC cards.
Just in case somebody plans to buy LX series card.
