The idea was to have linux on a usb stick that could be booted with machines 
using both legacy-bios and (u)efi boot and be able to use Xvesa, Xfbdev and 
full Xorg - so yes, the grub.cfg is shared and now, with insmod all_video, it 
works :)

I guess there's still the issue of 32-bit or 64-bit efi, but so few machines 
now use 32-bit efi I'm not too bothered about that.
