Korona is the live DVD combining KDE4 and OpenSolaris. I just uploaded the latest Korona 4.4.3 (with, eh, KDE 4.4.3) to genunix.org, it should appear there in a couple of hours.
Thanks to hnhn, the process list and other system info now work in ksysguard (https://bugs.kde.org/show_bug.cgi?id=200646)
Also, Korona is booting directly into a KDE session again.
When running the iso inside VirtualBox, I was observing high CPU utilization by the kernel, this is likely related to bug 12799; it runs ok on real hardware.
Also konqueror crashes on startup, which is weird as noone of those running KDE 4.4.3 from the bionicmutton repository has reported that.
Last note - the bionicmutton.org site (hosting the kde-solaris packages and mercurial repository) is down due to some severe hardware failures, please be patient.
