Description of problem:
This card has VGA, DVI and S-video outputs. The TV is detected as connected even when it's not. This causes VGA output not to work. When two monitors are connected (the 2nd one through DVI-VGA adapater), X startup takes ages (with monitor blinking many times), then finally desktop appears on DVI. xrandr shows that TV-1 is connected even when it's not:
Screen 0: minimum 320 x 200, current 3280 x 1024, maximum 4096 x 4096
VGA-1 connected (normal left inverted right x axis y axis)
1280x1024 75.0 + 60.0
1024x768 75.1 72.0 70.1 60.0
800x600 72.2 75.0 60.3 56.2
640x480 72.8 75.0 66.7 60.0
DVI-I-1 connected 1280x1024+1280+0 (normal left inverted right x axis y axis) 338mm x 270mm
1280x1024 60.0*+ 75.0 72.0
1024x768 75.1 70.1 60.0
800x600 72.2 75.0 60.3
640x480 72.8 75.0 66.7 60.0
TV-1 connected 720x576+2560+0 (normal left inverted right x axis y axis) 0mm x 0mm
Using "nouveau.tv_disable=1" kernel parameter makes VGA output work and also fixes slow X startup.

Steps to Reproduce:
1. Boot desktop-i386-20100418.17 with monitor attached to VGA output
Created attachment 408733 [details]
Created attachment 408735 [details]
When I boot with only DVI attached and nouveau.tv_disable=1 and hot-plug VGA monitor, it does not work. xrandr shows that it's attached, modes are detected properly and even signal is present (goes out of standby) but the screen is blank. However, when I attach TV to the S-video port, I see a unsynchronized image there.
This bug appears to have been reported against 'rawhide' during the Fedora 14 development cycle.
Changing version to '14'.
More information and reason for this action is here:
Does this still occur with the latest F14 kernel?
With desktop-i386-20101003.16.iso, VGA output works when used alone.
When both DVI and VGA outputs are connected at boot, VGA outputs incorrect signal (monitor OSD displays "input out of range") and xrandr shows that TV is connected even when it's not.
When booted with VGA-only and hot-plugging DVI, both monitors work fine. When the VGA is hot-unplugged, bogus TV is detected again and VGA output stops working until reboot.
Ben: note the nightlies still have kernel -28 as that was the last one submitted as an update, if any of the changes since -28 affect this, let us know.
This message is a notice that Fedora 14 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 14. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. At this time, all open bugs with a Fedora 'version'
of '14' have been closed as WONTFIX.
(Please note: Our normal process is to give advanced warning of this
occurring, but we forgot to do that. A thousand apologies.)
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen
this bug and simply change the 'version' to a later Fedora version.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we were unable to fix it before Fedora 14 reached end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged to click on
"Clone This Bug" (top right of this page) and open it against that
version of Fedora.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
