jan and speculatrix, it really depends on the device you own. Some have been in daily use with Ångström for years (spitz AKA SL-c3000), others just recently joined the band (collie AKA SL-5500). Some devices are wide-spread among devs and the general public, some less so. So it is quite natural to assume a very diverse state of device support in Ångström.
If you want to test things out, you should be prepared to flash your device and often more than once. Take the installation instructions from OZ
as a basis together with the Ångström files
. Go through the meta bugs in OE
which we use to cluster related bugs. You are very welcome to add your own, test old OZ bugs and generally get busy with testing.
One good advice is to use altboot to boot images from HD, SD or CF without touching the main Ångström install to save on reflashing all the time.
