Devices that need a driver are listed as 'Kernel driver in use:'
whether the driver is compiled in or not.

Devices that have their driver compiled in do not have the line
'Kernel modules:'

Devices that have neither line are controlled by the kernel but don't
need anything from the driver section.

I suppose there is the possibility that lspci could find a PCI device
which hasn't had a driver selected as module or builtin and then not
show anything. In this case I expect that the device wouldn't
function.

Hope this helps,
