I have probably figured out what's the problem, but i have no idea why...

I built the 3.2 kernel under debian wheezy because it failed to compile on 
squeeze. 3.4 can be compiled under squeeze ok now, but the result has this 
poor graphics performance. I tried to compile 3.4 under wheezy and it play the 
video fine.

So it looks that gcc is the problem here.

Thanks everyone for sending the reports, it helped a lot here.
