Пытаюсь собрать gentoo для кетайского нетбука на арме. Вобчем-то всё уже получилось и работает, за исключением одного - использую ядро, выдернутое вместе с модулями из андроида. Всё бы ничего, но это ядро категорически отказывается понимать и запускать блютуз-свисток, который мне очень хочется запустить, а также в нем отсутствует консоль и прочие мелочи.
Собрал ядро из исходников от WM - падает с такими ошибками:

Я не великий специалист в отладке, так что прошу помощи тут.
Подозреваю, что происходит такое от несовпадения архитектур, ибо исходники от WM собираются только для arm-none-linux-gnueabi (при другой архитектуре комиляция валится с невнятными ошибками), а гентушный stage собран для armv5tel-softfloat-linux-gnueabi.
