Do you build your own kernel?

As of about 2.6.18 the SATA driver has been moved out of the old IDE/ATA/ATAPI
driver (under 'Device Drivers'->'ATA/ATAPI/MFM/RLL support'), to its own libATA
(under 'Device Drivers'->'Serial ATA and Parallel ATA drivers')


>From menuconfig:
-------------------------------------------------------------
CONFIG_BLK_DEV_IDE_SATA:                                                        
                                                                               
                        
There are two drivers for Serial ATA controllers.                               
             
The main driver, "libata", exists inside the SCSI subsystem                     
           
and supports most modern SATA controllers.                                      
           

The IDE driver (which you are currently configuring) supports                   
           
a few first-generation SATA controllers.                                        
           

In order to eliminate conflicts between the two subsystems,                     
           
this config option enables the IDE driver's SATA support.                       
           
Normally this is disabled, as it is preferred that libata                       
           
supports SATA controllers, and this (IDE) driver supports                       
           
PATA controllers.
