To clarify:

i286 = 80286
i386 = 80386
i486 = 80486
i586 = Pentium
i686 = Pentium Pro, Pentium {II|III|4|M|D} / Celeron {M|D} / Xeon / Core
x86_64 = AMD {Sempron|Athlon64|Opteron} / Pentium {4|D} / Xeon / Core
         running in 64-bit mode

Binand, when you ask "detect" 64-bitness in a kickstart, do you mean in
the initial options to determine a repo to use, or in %pre / %post?  If
the latter, `uname -i` should suffice.
