That would need some tinkering in the driver, I think it should be possible for
us to expose sRGB capable RGBX visuals but .. risky. Every time we change the
visuals, some of the supported desktops (gnome/kde) tend to break. Let's leave
this bug open as a 'feature request/reminder' for this to happen. There's also
bug #92759 referring to the same issue.
