Hi Rodrigo, Happy new year and thank you for your fast reply! I am pretty new to kernel compilation in general and cross-compilation specifically, so I'm glad I can contribute to fine-tuning the description in the article.
Regarding the dtb file: I rechecked the process and noticed one more weird thing: When invoking 'make rpi_b_config' I get
'Can't find default configuration "configs/rpi_b_defconfig"!'
Removing the _b, so only 'make rpi_cofig' gives me a working config file. This config file does not contain any reference to "rev2"
I did some more research and was able to trace back the "rev2" to u-boot/board/raspberry/rpi/rpi.c. It seems to me that my board is not correctly detected. cat /proc/cpuinfo gives me

However, a precompiled rasbmc kernel correctly reports:
