Bug in Kwin + nVidia, is it possible to backport the fix?

[Christian González]

There are a bug in Kwin when using nVidia + TwinView + 2 monitors with
differents resolutions, see https://bugs.kde.org/show_bug.cgi?id=286146 and
https://bugs.kde.org/show_bug.cgi?id=285967

Thomas Lübking has commited a fix into branch 'master' (see
http://commits.kde.org/kde-workspace/c64f22c20ba8947ff1259ad2b3d14037f671...),
but AFAIK it's not backported to other branches. Is is possible to apply it
to KDE 4.7.3 in Fedora? It's really annoying to have Kwin forgetting
windows sizes and opening it semi-maximized all the time.

Thanks in advance.
