Oh wow.  An SiS card?  I don't know for sure whether those things have any 
accelerated 3D available at all.  The vast majority of stuff about compiz 
I've seen online talks about nVidia, ATi, and Intel cards.  Um... the ebuild 
for xf86-video-sis says that it uses the "dri" USE flag.  So it might work if 
you do "modprobe agpgart && modprobe sis" before starting X, and you have the 
appropriate Driver specified in xorg.conf .

That's a little weird too.  Usually it's :0.0 .

The kernel module that does DRI for the video chipset is either not loaded or 
nonexistent.  Or xorg.conf doesn't include Load "glx" \n Load "dri" \n 
Load "drm" in the Module section.  Hard to say what's really going on.  Try 
loading the modules, making sure that xorg.conf is loading stuff, and 
restarting X.  And if *that* doesn't work, it's time to get busy 
with /var/log/Xorg.0.log and possibly dmesg....
