Yes, I put "irqpoll" at grub's boot but I can't understand why irqpoll doesn't work.
Yesterday and today I'm trying with "options radeon modeset=0"
in /etc/modprobe.d/radeon-kms.conf, and although the performance is odd
according to the program (Chromium goes smoother than Iceweasel), the
direct rendering is on and there is only a problem with an IRQ:
dmesg:

Some lines have changed and they're different if KMS is on, but
according to /proc/interrups IRQ #16 is also from radeon.

I think the problem is my graphic card ATI Gigabyte HD4650 AGP 1GB. I'm
using it one or two years without problem until April 2011, when IRQs
problems started. In Windows XP there's no problem. And if I try
connecting an old ATI 9600 AGP 256MB in Linux there's no problem with
IRQs.
