Kernel config magic?

[John Heim]

Is there a way to take a stock kernel config and turn it into a FAI boot 
kernel config? I just cannot get my FAI boot kernel to recognize the sata 
drive in a machine. Who knows what box I have to check in the kernel config? 
But I know a ubuntu kernel recognizes the drive. Can I start with a ubuntu 
kernel config and make a FAI boot kernel?
