Ubuntu 8.04 is now released officially, but I still don't know if I got a final or just an RC of it. I installed it on the Pegasos, an then compiled an installer for the EFIKA, as my bugreport was not considered about adding EFIKA Ethernet driver to the network installer. All I changed compared to /boot/config is correcting the version string and enabling features needed to compile in EFIKA Ethernet support into the kernel.
Sound is not supported, I'll add it as soon as I'm sure, that I'm dealing with the final release. I hope, it will work, as I have patches for 2.6.22 and 2.6.25, and Ubuntu uses 2.6.24 :)
I'm currently dealing with

Tested KDE4 yesterday on Pegasos, it seems to work. It is somewhere in a stage where KDE4 in openSUSE factory about two months ago. It is all basic KDE 4.0, with default themes, no Ubuntu applets & co. BTW: XFCE on the EFIKA is quite useful for the same reasons: Ubuntu software management utilities do not start automagically making the whole system a lot faster and responsive.
