Can I use these no driver devices?

>dmesg | grep attached
pci0: <memory, RAM> at device 0.0 (no driver attached)
pci0: <serial bus, SMBus> at device 1.1 (no driver attached)
pci0: <memory, RAM> at device 1.2 (no driver attached)

What are those no driver attached devices?

Sincerely!
 
The <memory, RAM> entries aren't actually "devices", and can be ignored.

The <serial bus, SMBus> device should be accessible via:
# kldload smbus

Then, depending on the maker of the board, loading the correct driver from the following list:
# ls /boot/kernel/*smb*
 
I've never had any driver loaded for SMBus because I've never found any (FreeBSD) application that can use it on my machine. These applications only support specific motherboards and chips.
