Nouveau log (dmesg)

While trying to use Nouveau driver with display that sends incorrect EDID (only
FF, Samsung 226BW), screen flickers every ~10 seconds. Attached nouveau driver
log.

Everything works fine and very smooth, I can pass custom modelines to X server
to have 1680x1050 resolution, the only thing left that works very bad is this
flicker. If this matters, my GPU is GeForce 8600 GT.

Windows 7 uses 1024x768 resolution (same as Nouveau) while installing, but
without flicker.

Everytime log is filled up with new message, flicker happens.
