I would think a good list of things to include would be:

- lspci -v
  will not only list the PCI cards but includes which slot they are in
- lsusb -v (although I don't think usbutils is installed by default)
  includes things like firmware version for some devices and again using
  a different port will give different results
- dmidecode
  sometimes includes serial numbers, also can vary based on which slot
  things are in
- ifconfig -a
  includes MAC addresses
- smartctl -a [each hard drive]
  depending on drive, includes serial number, temperature, power-on time
  and count, random variables only the drive make understands

There is enough system-specific stuff in those to get pretty random
(once hashed).
