Kernel config for EFI boot

On my macbook 13" (late 2009, 6,1) with a GeForce 9400M (0x0ac180b1) when
booting nouveaufb kicks in and displays a garbled screen. Mostly black, some
greenish lines, some very unreadable text.

Interestingly, that only happens when I use the Macbook's native EFI mode (i.e.
*without* BIOS emulation).
If I use the BIOS emulation then nouveau works.

Typing blindly, I extracted the dmesg output, from an EFI boot:

#grep -i -e drm -e nouv -e fb efi-dmesg
Kernel command line: BOOT_IMAGE=/boot/experimental root=/dev/sda5 video=efifb

What's wrong? Let me know if you need anything, can even provide shell access
if need be.
