which controllers(devices) to disable in kernel?

[Perica Veljanovski]

Hi,

I bought a new pc with GIGABYTE GA-K8VT800 VIA K8T800 mother board (has 
ata, sata, raid) and a SATA IBM HDD and installed FreeBSD 6.0.

I'm building a custom kernel and I was wondering which 
controllers(devices) I need for my new kernel to support my motherboard 
properly?
Is there a way to see which devices my pc uses from the GENERIC kernel?

thanks,
