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?

Actually, USB is ok with PAE. I recently updated the PAE configs to not
disable PAE and at work we've run PAE kernels with USB enabled for a few
years now on 6.x w/o any problems.
