There is a cedega 6 topic somewhere in the forums think in general or x86 there is a easy way to install it.
Might also want to browse thru the how to forum under main forum for more info on basic linux questions.
Might want to have a fallback linux distro as alternative to sabayon as this does get complicated sometimes. Try pclinuxos.com very nice also rpm based same as ubuntu just looks much nicer and is a bit easier for new guy's than gentoo based / sabayon.
If you want to learn real linux sabayon is the right place.
Best of luck.
