You got something wrong in there.
You have to apply the patch in ata-modules.diff and replace /sys/dev/ 
ata with ata-modules.tgz.
Then you have to do a new config of your kernel as lots of files moved  
around, and then make depend all your new kernel.

I'll update the instructions on the site when I get home to it.
