Notice, how the log did not say NV4, NV04, NV5 nor NV05;
it said NV 0. Your NV34 is detected properly, though.

In that case you will be surprised to hear that quite many
people ask before reading TroubleShooting.

Sorry, I missed the link to the Ubuntu bug report.
The kernel log there shows that a conflicting driver is
loading:

[    3.772842] vga16fb: mapped to 0xc00a0000
[    3.773752] fb0: VGA16 VGA frame buffer device

vga16fb is specifically mentioned as conflicting in
TroubleShooting.

Could you try without vga16fb?


Thanks.
