F16: dual monitor woes (nouveau)

[Jerry James]

I upgraded my home machine to F16 on Wednesday, and liked it so much
that I decided to upgrade my work machine today.  That didn't go quite
as smoothly.

I've got a dual monitor setup at work, with what lspci calls "nVidia
Corporation G94 [GeForce 9600 GT] (rev a1)".  I did a fresh install
with a DVD.  After booting up, the initial screen (with the install
and troubleshoot options) came up on the left monitor; the right
monitor was blank.  After choosing to install, X came up on both
monitors, but the windows were displayed on the right monitor only.
The left monitor was black, but I could move the mouse over there.
The problem, though, is that the windows were apparently 2 monitors
wide.  The "back" and "forward" buttons were not visible, presumably
being one monitor width off to the right of the right monitor.  I got
by for awhile by tabbing twice and hitting Enter to activate the
"forward" button, but when I got to the part where I had to decide
which drives are data and which need to be formatted, I could not go
on, as the arrows to move drives between the two areas were off the
screen also.

So I restarted, chose the VESA option, got the left monitor only, and installed.

After installation, I removed /etc/X11/xorg.conf (which specified the
VESA driver), and rebooted.  But X still came up on only the left
monitor.  Xorg.log indicated a drm failure.  I found a new libdrm in
-testing, installed it, gave feedback on a typo in the udev rules, and
rebooted.  No change.

Here's are some excerpts from the logs, in case anybody has a clue as
to what's happening.  From /var/log/messages:

Does anybody have any clue what's going on here?  Thanks in advance.
