On http://wiki.debian.org/ArmEabiHowto
i read that to keep compatibilty with old eabi and eabi
kernel should be compiled with

CONFIG_ARM_THUMB=y
CONFIG_AEABI=y
CONFIG_OABI_COMPAT=y
______________________

On p51 i see only

# CONFIG_AEABI is not set
CONFIG_ARM_THUMB=y


Doesnt this break compatibility with old arm chroots? I cant chroot into an older arm etch for istance.
