If you change the SD partition to ext2, you have change the boot_args to
something like in the NAND flash.   The key difference, I believe, is
changing the rootfstype to ext2.

With Debian on a 2GB microSD card, here's my boot cmdline
(cat /proc/cmdline):

glamo_mci.sd_max_clk=10000000 rootfstype=jffs2 root=/dev/mtdblock6
console=ttySAC2,115200 console=tty0 loglevel=8 regular_boot
mtdparts=physmap-flash:-(nor);neo1973-nand:0x00040000(u-boot),0x00040000(u-boot_env),0x00800000(kernel),0x000a0000(splash),0x00040000(factory),0x0f6a0000(rootfs) rootfstype=ext2 root=/dev/mmcblk0p2 rootdelay=5
