Yep, the device table patch doesn't change any function, so your problem started from when 965G support patch has been in kernel. Carlo, pls try a kernel param of "pci=nommconf" to see if that could fix your hang. There might be a BIOS bug, as similar issue also happen like https://bugzilla.novell.com/show_bug.cgi?id=228683 I think for i965 we could have following patch to fix this, we may fail if no IGD device got detected.
