The recovery function should/probably/hopefully only check for the really required drivers for your platform.
So let me get this straight. What you are saying is that 90% percent of the using the /proc and /dev of the LiveCd will not cause any problems because they are very similar to the original system that I will boot into.

Am I correct in my assumption ?

initramfs on 2.4 kernel
