Its also a nice option for those without any FPU - for speed
reasons, but it would be nice for the FPU to work at least for
long enough for them to compile their binaries :)

The trouble is splitting that n ways
We already ahve NCR/SBC and HWDIRECT/MRG, which gives four

eight...
I'd expect any problems with UVM to be nailed pretty quickly
(hope hope), so with any luck it won't be an issue :)
