O possibly the sizes matched what i was using 2 years back ... might nit fit the new images
I've lost familiarity with uboot command line ....
I load them from usb with something that looks like this:

get populated somewhere along the execution of the script

ext2load usb ${dev}:$part 0x800000 ${usb_boot_dir} /uImage
ext2load usb ${dev}:$usb_dev_part 0x1100000 ${usb_boot_dir}/uinitrd
setenv usb_boot_address 0x800000 0x1100000
bootm $usb_boot_address

but they do look as if they are ok ....

The images got into /boot when by installing the packages from the versatile virtual machine (I then manually linked with the correct names my uboot looks for)
root at darkstar:/mnt/floppy/boot# ls
System.map@                 config-kirkwood-3.4.11  uImage-kirkwood-3.4.11  uinitrd-kirkwood-3.4.11
System.map-kirkwood-3.4.11  uImage@                 uinitrd@
root at darkstar:/mnt/floppy/boot#  md5sum uinitrd-kirkwood-3.4.11 uImage-kirkwood-3.4.11 
0ff11c800fa6745b04676787596246de  uinitrd-kirkwood-3.4.11
0c5e9a376a92e49863e2989875564a12  uImage-kirkwood-3.4.11
root at darkstar:/mnt/floppy/boot#

so I'm supposing that it's not an issue on how they got into the image.

anyway just incase anyone is intrested on the script I'm using for booting from usb stick if present (and correctly setup) or from internal flash here's a dump of printenv:
