dmesg from fedora 16

I have an Ati radeon x1550, and connected to that a DVI monitor (and another to
the VGA, but this bug is present also when only the DVI monitor is connected)
This bug appears in every distribution and kernel I tried, the last one is
fedora 16, but I tried debian 6 too and Archlinux with the latest kernel.
Description of problem:
DVI screen, if on standard resolution (1680x1050) blinks from the tty to the
Gnome dekstop, and especially when something like Firefox is made fullscreen:
I recorded a video to explain this better:
