We recently updated Kanotix with some new features and a LXDE variant. Just like the CeBIT release the LinuxTag special iso has Steam client preinstalled and nvidia and fglrx drivers autodetected in gfxdetect mode - even AFTER hd install - cool for usb (3) hds with lots of games. The kernel and mesa is patched with UVD support to try the early r600 vdpau drivers (mplayer and vlc is preinstalled to try). Official link to release notes:
