But later, Mike says his system does not have udev.

If Mike had known the 'basic' /dev entries needed, he probably could have used 
mknod to create them. He could have booted some Linux in a virtual system, 
archived /dev, copied it to the system he crippled and unarchived it.

To quote an old SF TV show, "Many such journeys are possible." :) :)
