Not unless your compiler emits code for the AMD/Cyrix 3DNow instructions!
(not likely)
The AMD processor is supposed to be an exact clean-room implementation of the
IA32 architecture (plus their 3D enhancements).
I think the chances of the problem being due to a difference in the floating
point register implementation are about, as you surmised, zero.
