I played around a little more with this.

This is either a Grub bug, or the kernel does not honor the fake bios thingy
created by grub.

I compiled the vbios i extracted (booting into bios mode with a live-CD) into
the kernel (just for fun), and it actualy found that, and could read that BIT
bios thing, however, it crashes as it does not find some other tables needed (i
assume i would need to somehow update those ...at least i think thats what grub
is doing...). The nouveauFB runs perfectly with that, but no X (and the kernel
crashes around like mad :-p)

I tried play around with nouveau_bios.c, as i found the vbios at address
0xc0000 in /dev/mem, but i get kernel errors about not be able to access that
address.

I keep on play around with it :-p
However, my knowledge about kernel stuff and hardware and acpi and bios is by
far not enough to do real debugging here.
