Subject: IDE disk runs just in DMA/33 with 2.6.20.2 on nVidia CK804 controller

Hi,
I reported this also for 2.6.20 kernel.
new libata with controller nVidia CK804 initializes the disk in DMA/33,
with with 2.6.19.5 and previous the disk is correctly inizialized in 
DMA/100.
Tha cable is OK, and with older kernels the disks runs without troubles.

The sistem has two sata disks on nvidia CK804 controllers, and then a disk 
as primary master, and a dvd writer (DMA/33) as secondary master)

here is lspci -vxxx
