ah.. yep I haven't yet compiled grub2 with efi,
(maybe)causing the stuckage with efifb, but then again
I tried with nvidiafb, and hit the same green colored
stuckage(but could be wrong), leading me to believe
just a simple adding of an address but then again

In any case I'll try to work this..
(be nice to get some patches sent upstream
for this area).
