If I might add, I believe that at least in some cases this could be avoided.
I have grub2-efi on a macbook pro, and I still get the cursor (the machine is booting directly to grub, no other bootloader, bios, etc is loading).
If instead I use rEFIt as the first bootloader, I can see the rEFIt menu without any extra modesetting or flickering, which leads me to believe that it would be possible for grub to do the same.
