Problemas instalación de paquetes y actualización Debian 6

Buenas,

Dispongo de una instalación de Debian 6 sobre arm: armel

El problema que tengo es que la instalación de prácticamente cualquier paquete me da errores, incluso con apt-upgrade.

He estado googleando y probado diferentes opciones, apt-get -f install + apt-get update + apt-get -f install sin éxito ya que apt-get update me genera el mismo error.

Debido a los warnings he probado a desactivar la concurrencia en el arranque (CONCURRENCY=none en /etc/default/rcS) pero parece que no funciona o que necesito desactivarlo en algún sitio más.

Como ya no sé que más probar ni por donde continuar, aquí os expongo mi duda a ver si me podéis echar una mano (gracias de antemano), os dejo las salidas de apt-get:
