Recommended by the vendor maybe. But I don't see any mode marked as
"preferred" in your xrandr output (a "+" flag would appear), which
likely means that the monitor doesn't say anything about it in the EDID
(what it sends to the graphic board), so the driver has no way to guess
which mode is preferred.

Did you try this?
>From what I read so far, your bug might just be the expected behavior:
the driver cannot tell which mode your prefer or which mode the monitor
prefers, so it just chooses one through a basic heuristic. If you don't
like its choice, please try the manipulation in the above link, you
should be able to force 1280x1024.
(with the earlier driver/server, the largest mode would have been
chosen, it's not the case anymore)
If you reproduce the bug where 1280x1024 does not get detected, please
send the corresponding log and the output of xrandr. That would probably
be a different bug though.
