>Description:
I tried loading the SMbus and I2C drivers as modules, but they fail to
attach to the devices:

[larse at nik: ~] cat /var/run/dmesg.boot | egrep 'iic|smb'
Preloaded elf module "/boot/kernel/smbus.ko" at 0xc06f3300.
Preloaded elf module "/boot/kernel/smb.ko" at 0xc06f3458.
Preloaded elf module "/boot/kernel/iicbus.ko" at 0xc06f3500.
Preloaded elf module "/boot/kernel/iic.ko" at 0xc06f35ac.
Preloaded elf module "/boot/kernel/iicsmb.ko" at 0xc06f3654.

[larse at nik: ~] dmesg | grep "no driver attached"
pci1: <display> at device 0.1 (no driver attached)
pci3: <base peripheral, interrupt controller> at device 0.0 (no driver attached)
pci4: <multimedia> at device 15.1 (no driver attached)
