No error? So your xrandr looks recent enough.

The mode you added above is available now.

That's probably a bug.

This is the RandR extension version supported by the server, not the
xrandr program version. I don't see how to get the program version from
the command line, apart from looking in
/usr/share/doc/xbase-clients/changelog.gz (or
...../x11-xserver-utils/changelog.gz).

It's already available in experimental in x11-xserver-utils (packages
are at ftp://ftp.debian.org/debian/pool/main/x/x11-xserver-utils) and
will be in unstable soon. Being in experimental does not mean "very
risky" here, it only means that the packaging changed a lot
(xbase-clients is split into multiple pieces) and had to be done
somewhere for testing before entering unstable.
Since you don't get any error when using --addmode, I guess you're
already running xrandr >= 1.2.1. Version 1.2.2 does not bring many
improvements.
