Enabled EFI options in kernel, removed old framebuffer drivers that were recently introduced but appear to cause problems. Reduced framebuffer to just three of which the simple frame buffer will probably be used the most. Added execute permissions to shredos_net.sh. And finally this is a rebuilt GRUB bootx64.efi which now includes the efi_gop and efi_uga grub modules build-in.
