vga=ask only works with the old linux loader, linux16.
But that isn't avaible in EFI because in EFI you can't load the kernel
with its 16 bit entry point.

you're searching in the wrong place. video and vga are options for the
Linux kernel.
Though vga= is parsed by grub, because the kernel excepts it's value in
a different format then in the standard commandline.
Note that `set gfxpayload=1024x768x16' (or whatever resolution/depth you
want) is now the prefered way with the new Linux loader.
