As all supported graphic adapters are supporting VGA we should list them in int10 (AX = 4F00h). Also clext.c and bochsvga.c are haveing a function named like is_XXX_mode() which checks if its a default VGA mode or a VESA mode. If its a normal VGA mode stdvga_set_mode() gets called.

This is a good idea. However, I don't think vbe_104f01() will correctly handle all the standard vga modes as it is coded today.
I will have a closer look at it during my following patches. If you want
you
can skip this patch.
Maybe it would be better to use this patch and update vga_modes array to reflect the modes we can do now.
