Libata seems to misdetect my cable.
I have double-checked and the cable is 80 pin...

ata1 is PATA ICH5 bus 1 with DVD-RW + ZIP and 40 pin cable
ata2 is PATA ICH5 bus 2 with extra HD + DVD and 80 pin cable
ata3 is real SATA ICH5 with boot HD

(mm, I chaged bios settings to get the box booting from the SATA disk)
