I can't see any EDID information in the output of `xrandr --verbose` or
Xorg.0.log. What are the correct resolution of your internal laptop
monitor (1200x800?) Would it be possible for you to connect your
external monitor (1440x900) via DVI and get the Xorg.0.log for that?
Since this was working in an earlier version of ubuntu, do you have the
possibility to start from an Intrepid LiveCD and attach `xrandr
--verbose` output and Xorg.0.log (preferably with the ModeDebug option
set)? Are you using your two monitors in mirrored mode or as an extended
desktop?

Newer versions of xorg (or the driver) rely more heavily on the EDID
information provided by the monitor that before. This is a standard that
virtually all monitors have supported since around 2001. Unfortunately,
many Vaio laptop panels don't support this, and these are the only
monitors I know about that don't. Occationally, the EDID information in
some models are slightly wrong, but in those cases it is possible to
make xorg work around it. Without any EDID information, it is not
possible to figure out what is connected at all.
