this fix seams to solve problems: https://bugs.freedesktop.org/show_bug.cgi?id=47535#c10
(I have Intel Core i5-2400 CPU (Sandy Bridge) processor with GPU and no other graphic card)

Anyway I reinstall the 12.04 from scratch and after I applied all available updates (still on kernel 3.2.0.24) I put the line
sudo intel_reg_write 0x2120 '0x1206800'
in /etc/rc.local.
After that (for 3 or 4 days now) I don't have any freeze, and even Google Earth work OK.

PS

I don't know if this is important but in Compiz (CCSM) under OpenGL I unchecked "Sync To VBlank" also.
