Screen flickering during boot

hi,
I've installed Debian 7.8 "Wheezy" but I encountered a problem.
When i boot is very rare to be able to enter the system without reboot at least another time,because the screen freeze,flickering like this:

(it's not my screen...but it gives the idea)
I Think that this can be caused by the fact that i don't have radeonATI driver installed,
but before doing anything i ask for your advice.

After your answer i've installed the packages (firmware-linux-nonfree only because the others where already installed) and i had to purge it because the system didn't boot anymore (all component load went fine until a screen of error come up) so i had to use ctrl alt f1 to enter the system and remove the package.
