If you are using the liveCD then the requirements should be no issue.

Those are the commands that should
be issued. However, a typo is easily made. It would be best if you could copy+paste the commands that you actually
issued. I.e. starting from the 'patch -Np1 ...' command up to 'make'.

I didn't do the step for x86_64 machines because that does not apply to me. Should I try using that step?
If 'uname -m' does not return x86_64 then you can skip this step.
