I have some additional information for this bug after discussing the
issue with NVIDIA. The bug that is occurring is indeed a bug in their
driver, but requires large changes that won't be happening very soon.
This bug however, is only being exposed due to a patch that is added to
compiz, 030_fix_screensaver. Looking at the changelog, this patch is
here for this reason:
compiz (1:0.6.2+git20071018-0ubuntu2) hardy; urgency=low
* debian/patches/030_fix_screensaver:
- never unredirect the gnome-screensaver window to prevent
breaking the keyboard grab (#145123)

-0400
That however, is no longer necessary since the bug that it was working around
was in the X server, and fixed by git commit:
http://cgit.freedesktop.org/xorg/xserver/commit/?id=a6a7fadbb03ee99312dfb15ac478ab3c414c1c0b
We absorbed this patch in the X server when merging from debian earlier:
xorg-server (2:1.4.1~git20080118-1) unstable; urgency=low
[ Brice Goglin ]
* Add 42_dont_break_grab_and_focus_for_window_when_redirecting.diff
to prevent password authentication bypass, closes: #449108.
[ Julien Cristau ]
* New upstream snapshot
+ includes the security fixes from the previous version
+ fixes regression introduced by the fix for CVE-2007-6429 in the MIT-SHM
extension (closes: #461410)

Once the 030_fix_screensaver patch is dropped, compiz works correctly on
NVIDIA cards.
