There are a number of architectures where you leave half of the performance of little things like memset and memcpy on the table without SIMD.
as a footnote: everytime in my career that someone has said "you never need floating point in X [kernel/network stack/some embedded thing/boot/whatever]," they've come back within a year to ask for my help with floating point library routines for X. So now you've cursed yourself =)
As an embedded developer let me say that the Cortex M4s with FPUs are worth their weight in gold for saving me from debugging fixed point libraries.

I never ever ever want to write fixed point numerics again.
I do embedded and systems development - you never need floating point in that sort of environment. It's only when you get into application domains that you need it.
