Confirmed here on an intel i945 too. I can't really remember what I did to have those crashes but it wasn't only during alt-tabbing (it was often when scrolling a page on firefox IIRC). I also tried ctrl+alt+backspace without any result, compiz was taking 100% of CPU and killing it + reloading X fixed the issue.
