Hi Tim,
I'm working on (ARM EABI) Gentoo for Zaurus, have you pushed the pxa vo driver
upstream or is there somewhere I can download it from?  For what it's worth,
I'm using gcc-4.2 with arm-iwmmxt-linux-gnueabi and using -ftree-vectorize for
the whole distribution, it's getting pretty good performance! ;-)
