Yokota-san's answer is correct here, which I've not repeated. however, atkbdc0 is a isa device as is fdc0. For some drivers it is easier to hack a pci front end that kicks the device into isa legacy mode. video is one (since it must support legacy things). pcic is another, because writing a native cardbus bridge code is a lot harder than writing a front end that kicks it into compat mode. but atakbdc and fdc, those really are isa devices.
