Do you have the latest and greatest Radeon driver installed, or using 
the default driver installed when you installed Lucid?

I have similar hassle with my 1920x1080 Viewsonic if I don't install the 
latest nVidia driver for my video card; install the 'proppa' driver and 
then I'm at the native resolution.
