I have a similar problem on Natty. If I open http://www.telekom.de/ in Firefox and leave the computer alone for some time (probably needs to have the screen power saving kicking in) X freezes. Graphics controller is Intel 82G965 (rev 02) and the system is 64-bit.
On my 64-bit laptop (Intel Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)) this problem nevver occured (on both Natty and Oneiric).
