SIMD is a general term, but you're right, I imagine it'll first
be SSE like dSetZero().  :)   ODE's source is available, so
anyone who knows 3dnow/etc can always add support separately...
but runtime autodetection glue so often gets forgotten...

I wish there was a good cross-platform solution for SIMD (does
anyone know any?).  GCC 3.4 (&3.3?) seems to have some low-level
cross-platform vector builtins, but I don't know how practical
they work out to be.  I don't think they begin to cover runtime
arch detection and code-switching though.
