I believe the reference to "the original system" means the *other* system
whose output was included in the email -- which does not show "AMD
Features" data. The "original system" does not show a reference to LM,
but the second system (whose output you quoted) *does*.
. . . which to me suggests that the processor is 64 bit, but the
"original system" for some reason does not recognize that fact.
