That's how it was explained to me too. Looking at the binary blob
part of the ia32-el package:
$ file /usr/lib/ia32el/ia32exec.bin
/usr/lib/ia32el/ia32exec.bin: MS-DOS executable (EXE), OS/2 or MS Windows
it seems that the implementation matches the slideware :-)
The rest of the ia32-el package is open source ... which should
provide enough documentation on how the OS-level code interfaces
to the instruction execution engine to allow it to be replaced.
