 the kernel will then look at the "supposedly ext3" filesystem on the
NAND flash, _treat_ it as an ext3 filesystem when it is in fact an
early and UNSTABLE ext4 filesystem, and dick with it.   i've already
had some fsck errors come up (about 500 of them), the consequences of
which i have _absolutely_ no idea about.

 but, if you are prepared to edit the smdk-6410.c to "swap over"
/dev/mmcblk0 and /dev/mmcblk1 by moving the order in the
platform_devices of s3c_device_hsmmc0 and s3c_device_hsmmc1 (it's as
simple as that) theeeeen you can create your own filesystem on the
SDcard, making sure that you have at least two partitions, THEN it
will be okay, because you won't be touching the NAND flash.

 remember that the u-boot params root=/dev/mmcblk0p2 we can NOT alter
right now (without risk).

 so, by simply swapping the order of the hsmmc block devices, SD card
become mmcblk0 :)
