Can't reproduce this on my i965. Need more specific steps on how to reproduce it.
The lspci output in comment #1 lacks PCI IDs. So if this is a HW-specific issue, there's not enough info to troubleshoot. You need to run 'lspci -vvnn'.
None of the log files display error messages. That makes it pretty hard to begin troubleshooting. Look in your /var/log/gdm/ and other log files in /var/log to see if you can locate some error message associated with the freeze. Check timestamps.
