kernel config: where is libata?

[Hugo Vanwoerkom <hvw59601@care2.com>]

Hi,

I can't use the Debian (Sid) kernels because VGA=<nnn> does not work on 
my box: gets 'invalid videomode'.
I can use Debian kernels with uvesafb but its companion v86d dies with 
my new GeForce 6200 AGP after a while.

But all works well when I roll my own kernel. Except then I cannot use 
smart with an external USB ATA disk I have.

It seems the libata kernel module is missing: I see that with 
2.6.26-1-686 and not with my kernel. But what CONFIG_ parm turns it on? 
Or where in make menuconfig does one enable it?
