Not true. NOR uboot can't read ext2, but most of the 2008 uboots can

It booted immediately because incorrect escaping ";" are to be escaped
or act as command separator ending the variable declaration and the next
command will run(all ; and $ and linefeed shall be escaped):
setenv menu_1 Boot from microSD (FAT+ext2): bootcmd=setenv bootargs
rootfstype=ext2 root=/dev/mmcblk0p2 rootdelay=5 \${mtdparts} ro\;
mmcinit\;fatload mmc 1 0x32000000 \${sd_image_name}\; bootm 0x32000000

Are you sure of the partition table on the SD ( mine has only two partitions
fat on partition one and ext3 on partition 3) and it boots the following:
bootargs_card=rootfstype=ext3 console=ttySAC2,115200 console=tty0 rootwait
glamo_mci.sd_max_clk=16373000 g_ether.host_addr=00:1F:11:01:1F:C2
g_ether.dev_addr=00:1F:11:01:1F:C2 regular_boot
mtdparts=mtdparts=physmap-flash:-(nor);neo1973-nand:0x00040000(u-boot),0x00040000(u-boot_env),0x00800000(kernel),0x000a0000(splash),0x00040000(factory),0x0f6a0000(rootfs)
level=loglevel=7
sd_image_name=/boot/uImage-GTA02.bin
bootcmd=setenv bootargs ${bootargs_card} ${mtdparts} ${level}
root=/dev/mmcblk0p3 ; mmcinit;ext2load mmc 1:3 0x32000000
