I could be talking rubbish here but isn't vesafb used as a fallback when 
you don't have correct drivers installed for the video card? I don't 
think you can control the video display by putting the settings wanted 
in grub. You may have to download the nvida drivers for your card to 
display properly. My experience of setting up the video resolution is 
using sax in suse, xconfigurator in redhat etc. Not sure what gentoo 
uses.
