You might try with the omap4_panda/MLO file rather than
x-loader-omap4-panda. It's my understanding that the MLO file shipped in
u-boot-omap can be used instead of x-loader.

If that works, the instuctions probably should be updated on the wiki.

Could you try the prepared images for debian-installer:

  http://d-i.debian.org/daily-images/armhf/daily/hd-media/SD-card-images/
  http://d-i.debian.org/daily-images/armhf/daily/hd-media/SD-card-images/README.concatenateable_images

I believe these images have u-boot written directly to the raw boot
media, rather than as files on the filesystem. They also use the MLO
file shipped with u-boot rather than x-loader. That *might* work better.
