Host -> Manage -> Hardware -> PCI Devices contain a lot of grayed out devices, most of them seem to be related to CPU, is that due to missing drivers for them?

Information of one specific item from esxcli hardware pci list indicates Module ID: -1, Module Name: None while something that is known to have drivers indicates Module ID: 50, Module Name: vmw_ahci. Does that mean item mentioned first doesn't have drivers?
