Okay, I removed the IDE one and tried your libata driver again.

What I maybe just did wrong on my first try, was loading it without any
parameters, as:
--------------------------
pata_it821x: Unknown parameter `it8212.noraid'
pata_it821x: Unknown parameter `it8212_noraid'
--------------------------
Loading without any parameters on this kernel resulted in:
--------------------------
pata_it821x: controller in smart mode.
ACPI: PCI Interrupt 0000:00:09.0[A] -> GSI 17 (level, low) -> IRQ 18
scsi3 : pata_it821x

---------------------------

Now I tried with "noraid=1", and now all seems to be working fine.

Thanks very much!
