You cna modify the boot options before the LiveCD kicks in... when you get to the splash screen, instead of waiting 30 seconds for the timer to count down or hitting Enter to launch the OS, you can modify the parameters by pressing F6 (I think) and then specifying your preferred desktop resolution using the "res=1280x1024" parameter.
Here's a list of various parameters you can pass... some of the might help with the other issues you've been having:

The only issue I had with Sabayon was that the majority of the coding and bug fixing seemed to be done by the one guy. They've got a pretty friendly forum though... it's just not as big as distros like Ubuntu.
