When using nographic, explicitly disabling vga is needed some cases since some qemu firmware (OpenFirmware ) defaults to std vga, and when vga is enabled then it disables output to serial and redirects that to vga which is by design, hwoever we expect the console output to go to serial when using nographic, therefore its important to disable vga with nographic especially on qemu based ppc platforms
