This is only a quick report for 20100922 DAILY_amd64_K on a Notebook HP CQ61-311AX
Live session working well no problems with Installer (Custom disk layout)
Playback render in XBMC (with Radeon HD 4300) is now working out of the box
Audio ATI SBx00 (IDT 92hd75B2x5)
RV710/730 Digital Stereo (HDMI) works out of the box, but because notebook is not permanently connected to HDMI device need to manually set-up audio to use notebook speakers, is not a real problem just the way the hardware is made and I will not mention the workaround from previous posts that I use
Otherwise SabayonLinux 5.4 x86_64 KDE is improving with each daily release
