Yes. At the moment I think that something based on that tree is
your best practical choice if you want neon support and certainly
if you need omap3.

No. This tree is currently tracking qemu upstream master and I am
using it as a way to provide tested arm patches to upstream in a way
that they can pull.

This depends on how long you are prepared to wait. Some ARM
fixes are starting to go into upstream. OTOH upstream's proposed
release cycle is about once every 6 months, with 0.14 due to
branch very shortly. So 0.15 ought to be much better for ARM
support but won't be available until middle of next year.

I'm currently focusing most of my effort on working with upstream
to get these patches accepted. I also have a blueprint for doing
at least enough maintenance/bugfixing on the maemo-qemu
package so it continues to boot the linaro images.
