I succesfully use 
with an u-boot environment, that can be create like this:

GTA02v6 #setenv menu_1 Boot from SD 2: setenv bootargs \${bootargs_base} 
rootfstype=ext2 root=/dev/mmcblk0p2 \${mtdparts}   \; mmcinit\; sleep 
2\; ext2load mmc 0:1 0x32000000 /boot/uImage-mmc2\; bootm 0x32000000
where bootargs_base is create by
GTA02v6 #setenv bootargs_base glamo_mci.sd_idleclk=1 
glamo_mci.sd_max_clk=12500000 rootfstype=jffs2 root=/dev/mtdblock6 
console=ttySAC2,115200 console=tty0 loglevel=5 rootdelay=5 regular_boot

Generally I don't change my boot environment.
All I do is copy the kernel into partition1/boot directory
and create symlink to it (e.g. /boot/uImage-mmc2).
The rootfs is placed into the according partition (e.g. /dev/mmcblk0p2).

Note: I use a SanDisk 16G card, which needs reduction of

Until current rootfs' get fixed, I dropped the 'ro' option in
the boot options.

I hope this helps a bit.

Cheers, Marc
