Works now, here's what I did:
Here's what I had to do to get sabayon to load w/ my Ati card. Warning- you will not have acceleration until after you install the program.
when the boot screen shows up, hit F5
add noaccelmanager to the options list and hit enter. the dvd will boot all the way. once at the desktop, I clicked on update installer. After that finished, you can click on install, and the graphical installer will load.
Once I installed Sabayon this way, it installed with acceleration and all options. tried a couple of the 3d games and they worked. They were a bit jerky, but then I have an old Ati 8500DV AIW which isn't the fastest card on the block
