I recently moved my openSUSE 11.4 system from the
proprietary drivers to nouveau. After much grief due to the
sometimes conflicting instruction on the Internet and
applications that placed out of date shared objects
(libraries) in /usr/local/lib which is searched first by
ld.so, I have it working on a 19" wide screen LCD monitor at
1440x900.
However, there is a distinct and periodic flicker that was
not present with the NVIDIA drivers and the font rendering
is not as crisp. I'm using the nouveau as supplied by the
standard repositories of openSUSE (zypper repos).
Attached is a file that contains the information relevant to
the installation.
Note that the change was made to get rid of the proprietary
software and since openSUSE 12.1 defaults to nouveau. I
intend to customize (make xconfig) compile the current
stable 3.x kernel to see if this fixes the problem. Other
suggestions would be welcome.

Honor, justice and humanity forbid us tamely to
surrender that freedom which we received from
our gallant ancestors and which our innocent
posterity have a right to receive from us. We
cannot endure the infamy and guilt of resigning
succeeding generations to that wretchedness which
inevitably awaits them if we basely entail
hereditary bondage on them.

Does it go away if you add
Option "PageFlip" "0"
to Device section of xorg.conf?
If yes, this is https://bugs.freedesktop.org/show_bug.cgi?id=42398
If not, please read http://nouveau.freedesktop.org/wiki/Bugs
and open new bug report with all mentioned logs.
