I promise not to top post anymore :)
Do you know why the problem I'm describing could be happening?
All other packages I have are i386.
I've taken the binary from bash i386 and I did ldd
I copied all relevant files to the livecd but it only works on i686.

I even force upgraded to glibc.i386 since some of the bash libraries 
were from glibc.i686

My only thought is that maybe libc.so.6 is the problem.
I did copy the libc.so.6 from the i386 into that i686 directory and 
overwrote it just to be sure but it still won't work.

Thank you for your help it is much appreciated.

Below is the ldd of the standard bash binary from Centos
ldd /bin/bash
        libtermcap.so.2 => /lib/libtermcap.so.2 (0x0083e000)
        libdl.so.2 => /lib/libdl.so.2 (0x007d4000)
        libc.so.6 => /lib/tls/i686/libc.so.6 (0x006be000)
        /lib/ld-linux.so.2 (0x006a7000)
