VESA should show you a screen, which should be perhaps useable for text-mode 
CLI and maybe some basic graphics (slow, very slow, as in repaint entire 
screen line by line for any update). I have an old laptop with an ancient 
radeon chip which is so old support has actually been removed so that VESA 
is the only way I can use it. It does work with GUI desktops, just slowly.

VESA mode(s) will never give you any support for GL and there won't be any 
way (to my limited knowledge) to run code that depends on GL libraries.
