You don't have to. It's already underway :)

It's kinda integrated into BetaPlayer. It's not just separate assembly file, I uses 
dynamically generated ARM code.

Btw what do you know about prc-tools development? It seems the latest 2.3 version
is very old. I'am currently compiling  new modified gcc cross compiler for myself
using gcc 3.4.3 with making the R9 ARM register free for use (and restoring it 
manually before every OS callback). Loosing two ARM registers (R9,R10) with 
the default armlet system on PalmOS is kinda too much for me :)
