I am also experiencing this issue.

I am booting the kernel EFI stub using refind on my macbook 5,1.
This model is fitted only with nvidia 9400M.

I use nouveau.noaccel=1 as a boot parameter.
This way I at least get a scrambled screen after the efifb handover.
Otherwise the screen would just freeze.

When I can see that the init script finished, I blindly log in and type
pm-suspend.
Than I press the power button to wake from suspend.
Now, I am presented with a usable screen, but not accelerated.
I can also run X.

I am running Gentoo. Tried vanilla and git kernels in and out of tree without
luck, from version 3.7.4 till 3.10.1

Clearly it is a handover problem. If there is any useful information I can
provide let me know how.
