Kernel messages after loading noveau module

GT 240 card (10de:0ca3), works nice with proprietary driver
Gentoo kernels 3.2.12 and 3.3.8 Fedora 16, 17 with 3.4.4 - same behavior, even same last messages.
Almost immediately after loading nouveau kernel module the system hangs completely, even Alt+SysRq keys don't work. Few times it looked like panic - keyboard LEDs started blinking, but usually it just hangs.
I used systemd.unit=emergency.target to isolate the situation - boot to minimal system and run modprobe nouveau manually, netconsole to extract messages - strangely, it got nothing more than I can see on the screen. I'm afraid nothing useful is there, last one being "[drm] No driver support for vblank timestamp query.", but I attached log of all messages which appear after executing modprobe. Maybe, I can get more debug output somehow?

Can you see if newer kernels work better? If not, please post a more recent log and your VBIOS (see http://nouveau.freedesktop.org/wiki/DumpingVideoBios/).
