which part of THEY ARE NOT FILES are you missing here?

thats the kernel reporting the ACTUAL cpuinfo. you can''t change that.  
ditto interrupts, etc.

$ cat /proc/interrupts
           CPU0      
  0: 2214281030          XT-PIC  timer
  1:          2          XT-PIC  i8042
  2:          0          XT-PIC  cascade
  6:          6          XT-PIC  floppy
  7:          1          XT-PIC  parport0
  8:          1          XT-PIC  rtc
  9:          1          XT-PIC  acpi, uhci_hcd:usb2
 11:     218548          XT-PIC  eth0
 12:          1          XT-PIC  uhci_hcd:usb1
 14:    4659843          XT-PIC  ide0
 15:   19337609          XT-PIC  ide1
NMI:          0
LOC:          0

what possible sense would 'copying' that to another system make?  I go 
to a different computer...

  # cat /proc/interrupts
           CPU0      
  0: 1078260604          XT-PIC  timer
  1:          3          XT-PIC  keyboard
  2:          0          XT-PIC  cascade
  7:          0          XT-PIC  usb-ohci
  8:          1          XT-PIC  rtc
  9:   75485990          XT-PIC  aic7xxx
 10: 1754046926          XT-PIC  eth0
 14:        131          XT-PIC  ide0
NMI:          0
ERR:          0

and the different devices are on different IRQs, never mind the IRQ 
counts being different.

anyways, most of whats in /proc is readonly.
