For sure, there is not much point in starting on old code (the "stable"
2.6.16 series /may/ turn out to be an exception one day).

An x86_64 port will be highly welcome! Feel invited to post I-pipe
related topics also to adeos-main@gna.org.

One hint that may ease testing/debugging: Have a look at qemu for
x86_64. At least on x86, it already helped me a lot to debug weird
kernel issues without long run-instrument-build-rerun cycles. All it
takes is a minimal system image for a target. You can easily attach a
debugger to the kernel, and you can even emulate SMP (though debugging
is not perfect in that case). Of course, you cannot identify latency
issues this way, but you will likely already be happy when things don't
crash anymore. :)
