Please show the point where it takes time. You have a log in

As far as I know this is not possible (I might be mistaken). Either you
remove the hardware or the support for this piece of hardware.

devfs provides a kind of virtual file system which will be created in
respect of the devices that are known to the kernel. Everytime you
unmount devfs all changes that were directly made to /dev are gone.

The 'CD9660' option in the kernel configuration is a file system support
and has nothing necessarily to do with support of hardware devices. I
guess you mean 'device atapicd'.
