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?

Does it only blink on the 1680x1050 mode or all modes on the DVI monitor?

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.
