RandR is broken to that respect - it selects a resolution that is as
large as possible, and 1280x800 is apparently possible with the default
timing limits...

This is - to the best of my understanding - a RandR, and not a driver
related issue. Best to complain about it in a bug report, or on
xorg-devel.

You have to add the monitor with

  Option "monitor-DVI-I_1/analog" "MyMonitor"

in the device section. The monitor referenced in the screen section is
ignored with RandR. This is a FAQ.

If you want to add new larger modes dynamically, you have to add
"Virtual" as described in the FAQ section of the radeonhd wiki.
