efiemu64.o works on x64 machines only. efiemu32.o works everywhere and I
recommends using it.

This command is eliminated in the last patch.

You may also just do efiemu_pnvram with no file as an argument

Unfortunately there is no consensus yet as to how graphics should be for now
it's the following interface:
[on pc only:] vbe_mode=0xYYY # desired vga mode
The blind mode in this patch doesn't work correctly, you are likely to get
a mysterious panic due to memory overwrite
I have done some improvements on the patch and will send it after few tests
