Comment # 7 on bug 88868 from 
OK, so this is (part of) your problem:

nouveau  [  DEVICE][0000:01:00.0] BOOT0  : 0xa1a0900d
nouveau  [  DEVICE][0000:01:00.0] Chipset: nForce (NV1A)
nouveau  [  DEVICE][0000:01:00.0] Family : NV10

Once this happens, nothing will work. The boot0 seems swapped, it should read
back 0x0d90a0a1, which would be a NVD9 (GF119) which is a very reasonable
chipset for a GT610 or GT520 to report. [Unlike NV1A which is a GeForce2 IGP
from ~2003 or so.]

Normally we kick the card into the proper LE/BE mode (which byteswaps all the
register reads/writes at the hw level), but perhaps that's not working for some
reason? I assume this is a BE box, and there's not a whole lot of testing that
goes on (esp for newer cards) on BE. Another thing to note is that nouveau
requires 4K pages (not for any great reason, but there's a lot of confusion
inside the driver regarding whether system or gpu pages are being used, and
PAGE_SHIFT/SIZE aren't universally used in the right places).
