Ultra ATA133 ?

А сабж вообще как включить? Мать ASUS A7V8X-X, KT400/VT8233-8235,винт
Samsung SpinPoint P80 P0802N 80Gb. В спецификации написано. что он ето
поддерживает. Ядро 2.24.25. При загрузке пишет:
Uniform Multi-Platform E-IDE driver Revision: 7.00beta4-2.4
ide: Assuming 50MHz system bus speed for PIO modes
VP_IDE: IDE controller at PCI slot 00:11.1
PCI: No IRQ known for interrupt pin A of device 00:11.1 - using IRQ 255

hda: SAMSUNG SP0802N, ATA DISK drive
blk: queue c036a960, I/O limit 4095Mb (mask 0xffffffff)

И потом:

hda: attached ide-disk driver.
hda: host protected area => 1
hda: 156368016 sectors (80060 MB) w/2048KiB Cache, CHS=9733/255/63, UDMA(100)

У ядра опции idebus=50б ide0=ata66. На idebus=66 говорит, что недопустимое значение. И как врубить Ultra ATA100? Или оно уже работает? В /proc/ide/via пишет:
