Someone just asked me and I didn't know what to tell him...
an Opteron machine, how x86 is it? I understand it's supposed to be
fully backwards compatible. does it mean I can just take an x86 regular
32 bit kernel and binaries and run on it? is 64bit an option or a must?
how does it mix? can old 3

As for mixing 32bit and 64bit: AFAIK you can't mix 32bit and 64bit code
in the same process. Thus a 32bit binary needs a separate set of
libraries. Other than that, it works just as well.
umm... why? the CPU doesn't rea

Now, if 64bit is anything like it, you actually can't mix them in the
same process. Too much work to switch between them. Different memory
addressing modes, etc.
I think that's the reason - different and incompatible modes.
I distinctly remember this in the context of why A
