>Description:
The ICH6 SATA controller found on Dell Latitude d610 laptops is not supported by the ata driver. After patching with the diff below, the kernel sets the speed of the device to UDMA100. I'm not sure if this is the right thing, but since I'm not familiar with the ata code, I leave this for your appreciation.
