I couldn't get this to work on my n810. I was able to format the the internal card in windows xp over the usb cable, but when I reboot the tablet and disconnect the cable, nothings changed. The same files/directories are there, the card is mounted in read-only mode, and I can't disable the swap (even xterm as root entering "swapoff -a", which doesn't report any problems, but it doesn't actually disable the swap memory usage).
