I suspect the experimental limitation doesn't come from the 32 or 64 bit 
binary, but from the 64-bits kernel. I understand certain 16-bit mode 
things aren't possible when the system runs in 64-bit mode, so that's 
why the emulation is necessary for certain parts then. This emulation 
feature is still experimental.
