Modules from the original firmware contain references to some debugfs_* symbols (s. r11992 for details). These require CONFIG_DEBUG_FS to be enabled, which is not the case in AVM's .config.

Tree like overview

Tree like overview of all kernel sources published by AVM so far (as of 2014-09-23) for 05.2x, 05.5x, 06.0x, and 06.2x firmwares (generated using tree -d -L 4 --noreport | grep -Ev "linux-2.6.(28|32)"). 

Legend:
 * listed directly under 0X.YZ => unique kernel-source-package not equal to any other
 * listed under BOXID.0X.YZ-identical => kernel-source-package is identical to BOXID.0X.YZ
