Проблемы при установке поддержки SATA-винтов в ядре

Пытаюсь скомпилировать ванильное ядро 2.6.23 для gentoo 2007.0 для ноута Toshiba Satellite M100-150, в котором стоит SATA винт (он может работать как SATA так и как PATA(ATA-7)). Чипсет 945PM, ICH7. У меня не получается добиться от ядра определять винт как SATA. Если не ошибаюсь, то оно вообще загружается в PIO. Подскажите что сделать. Ниже привожу часть dmesg от этого ядра, а следующее - dmesg от knoppix 5.x - в принципе то, чего я хочу добиться.
