that woudl be fantastic, it should be able to automatically put the vesa code in if no drivers can be loaded. Like I said my mom should be able to install sabayon. its alot different if you load into a gui and it doesnt look right yet its still funcitonal. I can load windows 98 on my machine and it looks crappy cause theres no nvidia 8800 driver but I would be able to open a browser and download the drivers and fix any other problems using the gui.
You mention it automatically loads the VESA driver if no driver is found but this is not the case as it cannot find a driver for my 8800 and it simply dumps me to a text console because it couldnt load any drivers.
