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:

Does booting with radeon.disp_priority=2 on the kernel command line in grub help?
Comment 3 ter4py 2012-04-02 07:57:35 UTC
It doesn't help at all.

Does it only blink on the 1680x1050 mode or all modes on the DVI monitor?
Comment 5 ter4py 2012-04-02 08:25:14 UTC
Only in the 1680x1050 mode that way.
But it might happen very rarely on 1480x900. 
I'm not sure about this though, it didn't happen recently.
