Don't worry, you've been cc'd.

Use xvidtune, and capture into a textfile the modelines that each of your
modes actually ends up at. Don't forget to use Next to go through all of
your resolutions.
Upgrade if that's still what you'd like to do, making sure to keep a copy
of the slink .deb file for your X server so you can easily go back if this
doesn't work. (in other words, don't keep it someplace where it might get
wiped, like /tmp or /var/cache/apt/archives.) Before launching into your
newly upgraded X session, go into your /etc/X11/XF86Config file, and create
a new Monitor section. This new Monitor should *only* mention the modelines
which you already were using. You can also check that the Screen sections
mention all the sizes you want in the right order - and you should change
the monitor ID they point at, to the new Monitor you created. Oh yeah, your
new Monitor section should also correctly set your HorizSync and VertRefresh
values.
That should defeat X's normal autoselection, in favor of known-good information.

Best of luck, let us know how it goes.
