I had earlier written about not being able to boot from the CentOS Userland image on my Raspberry Pi. It is a Model B+ 512MB from element14.
It failed to boot as previously, and no messages appeared on the screen. I did get the colorful splash screen that shows the kernel was not able to be loaded. Also the green led would blink 7 times in a row, again indicating a problem loading the kernel.
At this point I did a search to find out why this image doesn't work, although every other image I've used worked flawlessly. The md5sum matched and fsck showed no problems with the filesystems. I think the answer is at the bottom of this webpage.

It shows that for the models B and B+ some extra files must be copied to the boot partition. I tried unsuccessfully to find bcm2835-rpi-b-plus.dtb on the root partition.
I'd be glad to assist with testing if someone can get me a copy of the missing files.
