SMBus driver

Hi,

pciconf -lvbe

none0_at_pci0:0:20:0:    class=0x0c0500 card=0x21f7103c chip=0x780b1022
rev=0x3a hdr=0x00
    vendor     = 'Advanced Micro Devices, Inc. [AMD]'
    device     = 'FCH SMBus Controller'
    class      = serial bus
    subclass   = SMBus

I have 'device smbus' in KERNCONF.
I would love to know how to correct this. I looked in sys/dev/smbus but
have no idea which file to edit or where to begin understanding why its
none0.

Thank you
