Now I have upgraded the Linux kernel to 2.6.36. I can now make the VGA-0 go from powersave to an odd shade of greenish gray if I use KDE's systemsettings to change the screen. I could not replicate that using xrandr, though. So it seems I am still stuck with one screen if I want to use the free driver.
