the problem of black screen seems to be resolved adding the following patch:
Adding nv18 card identifier to Powerbook specific quirks
in nouveau kernel module:
diff nouveau_bios.c.old nouveau_bios.c
3199c3199
<       if (script == LVDS_RESET && ((dev->pci_device & 0xffff) == 0x0179 ||
(dev->pci_device & 0xffff) == 0x0329))
---

> ||(dev->pci_device & 0xffff) == 0x0189 || (dev->pci_device & 0xffff) == 
> 0x0329))

same as in xorg driver:

diff nv_bios.c.old nv_bios.c
2592c2592
<       if (script == LVDS_RESET && ((pNv->Chipset & 0xffff) == 0x0179 ||
(pNv->Chipset & 0xffff) == 0x0329))
---

> ||(pNv->Chipset & 0xffff) == 0x0189 || (pNv->Chipset & 0xffff) == 0x0329))

Now both framebuffer console and Xorg work.

But there is another problem with TV-out:
When turned on the TV output is in contrast with the LVDS output and set the
screen resolution of 720x576 on the console framebuffer.
