I would first like to ask, would the "int32 patch" suffice to your  
needs?

I've had the non-FPU issue on ARM, and that was the way to get it  
solved. My suggestion would be a float+int32 patched Lua, where you  
get the best of both worlds. This happens without the script level  
knowing anything, speed is boosted 2-5 times from that of non- 
patched, emulated FPU operations.

that! ;)
