    Seems like Samsung drivers recognize incorrect modes and misrecognize correct ones... Just revert the patch with patch -R for now.

    Could you make an option to output framebuffer to a file or a stream instead of the screen? Maybe if you could move it to /sdcard/.framebuffer/fb0 we could get faster screenshots.

    Code:
    for (n00b n : mSamdroid) {
    if (!n.findAnswer()) {
        n.useSearch();
    }
}

    I believe that we actually want the framebuffer to output to the screen, because this is what the framebuffer is for. You can dump framebuffer contents by executing 'cat /dev/graphics/fb0 > /sdcard/screenshot' in adb shell.

    Btw. The frame buffer resides in RAM, so moving it to a slow storage like SD wouldn't do any good (and still this is just impossible).

    BTW. Do you know how to see kernel boot messages instead of the "Android_" text at boot?

    You need a little kernel patch to force your own command line instead of the one passed by the bootloader to redirect kernel output to the framebuffer instead of the default serial port. I will attach it here a bit later.
