There is already kernel level fpu emulation for x86 and there is  
already vfp, fpu, and even neon in qemu.  While I don't think it would  
be trivial to do, it doesn't sound quite as hard because you aren't  
going to have to reverse engineer the whole thing. I'm not  
volunteering either as I assume you mean -working- fpu/vfp support. :)
