Well, if you start fslaunch / setup, goto the speed tab. Here you can see if the ppc (warpos) is used, else the 68k is used for sound & gfx.
The main program actually doesn't use powerpc.library at all, but some external libs do.
There should also be an update, which you can download from the hyperion site (when registered).
This one was free [years ago], don't know if it's still there.
