X log

My X log tells me the following:

(II) RADEON(0): Max desktop size set to 2560x1600
(II) RADEON(0): For a larger or smaller max desktop size, add a Virtual line to your xorg.conf

Which is great. This means, I can use my two monitors in dual-head in their native resolution without needing to use the "Virtual" option in xorg.conf.
Or? I have a problem with my 1280x1024 monitor getting mode 1024x768, as I have specified in bug 15317. This means I have to set it manually using xrandr:

$ xrandr --output DVI-0 --mode 1280x1024 --rate 75
xrandr: screen cannot be larger than 2048x1600 (desired size 2304x1024)

Now it says max desktop size is 2048x1600 when my x log says 2560x1600...
Well, it works by using the "Virtual" option in xorg.conf (which noone should ever need to specify I think), but the log (or xrandr) shouldn't give me incorrect information.

Almost certainly not the case anymore.
