OpenZaurus
Some time ago new kernel hacker joined team of people working on 2.6 kernel for Zaurus machines — Thomas Kunze gave us SD/MMC driver for collie and works on other subsystems to get this machine working. As result collie got added into list of Ångström supported devices and test images were generated.
Also during last time people were asking Koen Kooi when Ångström is going to be released. He usually answered that it depends on OpenZaurus release plans (OZ first).
But they lack developers to work on two distros in one time. Release of OpenZaurus 3.5.4/3.5.4.1 took me few months of work as I had to organize beta testing program, build images, fix bugs, find someone to work on documentation, build feeds. Then due to limited access to main mirror I had to work on upgrades feeds. Those tasks will be split to more people in Ångström.
