Yes, that is what I thought. Right now, I am just commenting them out,
now I know what people mean when they say they are running a
trimmed/clean kernel.

I did see one potential issue...

# USB support
device          uhci            # UHCI PCI->USB interface
device          ohci            # OHCI PCI->USB interface
device          ehci            # EHCI PCI->USB interface (USB 2.0)
device          usb             # USB Bus (required)

I see all of these with nodevice lines in the PAE file. Although I have
USB ports, I don't use them, but I was concerned by the 'required' on
the last one, is it OK to remove? Also, would I then need to disable USB
in the BIOS to avoid errors?
