Not sure that is exactly going to be without side-effects for you
though. Your performance will probably drop significantly if you move
away from hardware floating point.

I've also had some issues with the alignment stuff. Added my notes to
the wiki just as some jots before sitting down and trying to tackle
the issue properly when I get some time with some vodka in hand!

Daniel.
