Not really, since that requires mode switch (similar to the "enhanced
386 mode" back then), which the kernel normally won't allow a normal
application to do. In the long term it's probably more realistic to have
a small 32-bit decoder prog that passes all the data around via pipes.
Maybe this is even already possible now by doing something similar as in
the TOOLS/mplmult.sh script...
