    SubjectRegression: black screen on VGA w/ nouveau in Linux 3.3
    Hi folks,

    Just upgraded to Linux 3.3 on my desktop and noticed that the VGA output
    on my card w/ nouveau is totally black (both at the console and in X).
    Almost everything appears to work normally: DPMS works, modesetting
    works, DDC works... all messages indicate that things are working --
    just the image is completely black.

    The VGA is one of two outputs in use: the other (DVI) output works
    normally. The card also has an unused TV-out port, FWIW.

    The card is an NV36 generation (Geforce FX5700 AGP). This is a
    regression from Linux 3.2 -- unfortunately, bisection has proved
    extremely difficult because the intermediate kernels git is asking me
    to test panic immediately on boot (and compiling Linux takes a fairly
    long time on this box too). The failed attempt went like this:

    git bisect start 'drivers/gpu'
    # bad: [c16fa4f2ad19908a47c63d8fa436a1178438c7e7] Linux 3.3
    git bisect bad c16fa4f2ad19908a47c63d8fa436a1178438c7e7
    # good: [805a6af8dba5dfdd35ec35dc52ec0122400b2610] Linux 3.2
    git bisect good 805a6af8dba5dfdd35ec35dc52ec0122400b2610

    (I stopped at this point)

    I'm running the latest git xf86-video-nouveau, but since the issue
    occurs at the console it's probably not too important...

    Let me know if you need any more info,
