I installed linux-image-2.6.30-freezetest1, linux-image-2.6.30-freezetest8 and linux-image-2.6.30-freezetest9, as per https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/447892. I tested freezetest1 and freezetest9 for over 1 1/2 hours without lockup. I removed "acpi=off" from the grub kernel line in both cases.
The kernels behaved well, as far as I can tell, except that I had to boot using the recovery mode. Otherwise, boot hung at the point where the listing of modem drivers occurs.
As version 9 didn't freeze, I didn't bother with testing version 8.
