I had an issue similar to this on my Toshiba Laptop.  I ordered it under 
the impression that the drives were all IDE as SATA support was not that 
great at the time.  Both my HD and DVD drives came up as SATA devices 
even though the information stated both were IDE from the web.

Now the issue was traced to the BIOS but there were no changes allowed 
in the BIOS for this.  I had to set a kernel flag (cannot remember and 
the laptop is not here) for the pata support to work properly.

I traced it through the ICH6 {?} controller information.

Sorry I cannot provide a deeper answer.

Look at ata_piix
