Display corruption with nouveau on an NV36

Description of problem:
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Crap - stray 'enter' key. Sorry for the spam. Anyway --
I get display corruption (see attached screenshot) on my NV36 when using nouveau. It disappears if I add " "EXANoUploadToScreen" "true" to my xorg.conf (or turn off acceleration entirely.) Turning off composite makes no difference. Using a compositing window manager makes no difference. Turning off AGP (turning AGP to minimum in BIOS, booting with agp=off, and modprobeing nouveau with noagp=1) doesn't make a difference.
I've attached my Xorg.0.log as well.

Can I see the output of the dmesg command after you've seen the corruption appear?
I'm assuming you're "quotemstr" from #nouveau? You mention it only happens at 16bpp, that's useful information, I will look into this. But, the dmesg info could still prove useful.

This is fixed in rawhide as of xorg-x11-drv-nouveau-0.0.15-2.20090805git712064e.fc12. Are you still using F11? If so, I'll backport this tomorrow, otherwise I'll close as fixed in rawhide.
I'm still using F11, so if you have time, I'd love a backport. Thanks!
xorg-x11-drv-nouveau-0.0.12-41.20090528git0c17b87.fc11 has been submitted as an update for Fedora 11.
xorg-x11-drv-nouveau-0.0.12-41.20090528git0c17b87.fc11 has been pushed to the Fedora 11 testing repository. If problems still persist, please make note of it in this bug report.
If you want to test the update, you can install it with
su -c 'yum --enablerepo=updates-testing update xorg-x11-drv-nouveau'. You can provide feedback for this update here: http://admin.fedoraproject.org/updates/F11/FEDORA-2009-8398
This message is a reminder that Fedora 11 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 11. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '11'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 11's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 11 is 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 please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
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.
The process we are following is described here:
Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
