pch.shot Bro - That can not happens!
First the Build is on the OpenSUSE site with there software for the Remixing.
then I have made test's in the VDrive on the site there +made test to the ISO on my HDD.
Now to me it looks like you did not start-up with safe mode.
You need to run the install process with the safe mode - because the missing Drivers for the Video Card.
you must have more then 1 GB of RAM on your machine to get all to work like Compiz and so on.
BTW - if you run the 64bit on your VBox please do it with OpenSUSE 64bit option.
you remember that there are 2 options on the VBOX for any system right.
so if you run the system with 32bit that is no go.
Here is the Build packages on my system just for one time to show the ppl what there is inside the system.
and to understand the way the system support the audio/video and software.
