I don't think it is bad disks. I tried all the Sabayon 8 ISOs acquired via bitttorent and 8 Weekly ISOs, both 64 bit and 32 bit. Only the Gnome and XFCE load the Xserver. The others give the error posted above. Sabayon does not configure the Radeon open source driver correctly for my hardware and appears to switch to the VESA fb in an inappropriate way so I get no working X server.
I tried 3 other distro's live CD/DVD and they all generate a working X server.
I first tried Puppy Linux (current version called Slacko-5.3.3 because it is based on Slackware) It has an X configuration wizard so you can try various setting if the default does not work. I could not get the Xorg Radeon driver to work but as soon as I selected the VESA FB, the X server came right up.
Next I tried PC LINUX OS, I have used it in the past and it is excellent at hardware detection and configuration. It booted up with the X server working. It used the proprietary ATI fglrx driver. It also installed the ATI Catalyst software to manage video. While it is very good at dealing with the hardware, it is also very slow. It must be trying many different thing to get the hardware properly configured.
Finally I tried Gentoo live dvd AMD64 multilib 2012.1. It booted up with the X server working. It appears to be using the Xorg Radeon driver and has it correctly configured for my hardware. I could not get my usb wifi adapter (ath9k, which works fine with the others including Sabayon) to work, dmesg has an error that it could not find the firmware (htc_9072.fw) which makes no sense since the firmware is in /lib/firmware where it belongs.
The X server problem appears to be specific to Sabayon.
