Why are you using /card? On my Nanonote, my SD card appears in /mnt.mmcblk0p1:

root at BenNanoNote:/mnt/mmcblk0p1# df
Filesystem           1K-blocks      Used Available Use% Mounted on
ubi0:rootfs            1904680     31884   1872796   2% /
devtmpfs                   512         0       512   0% /dev
tmpfs       .             14240        24     14216   0% /tmp
tmpfs                      512         0       512   0% /dev
/dev/mmcblk0p1         7753728        64   7753664   0% /mnt/mmcblk0p1

and I have no problems creating directories and files in it.
