I downloaded and booted from the hardy-desktop-i386 alpha-5.

The refresh rate was ~30Hz.

I installed the new intel driver as mentioned above (http://mirrors.kernel.org/ubuntu/pool/main/x/xserver-xorg-video-intel/xserver-xorg-video-intel_2.2.1-1ubuntu2_i386.deb)

Ctrl-Alt-Backspace restarted X and logged me in again.

compiz crashed. This seems to be a reported bug (183685). It seemed reproduceable (well, it happened twice in a row). There seemed to be no impact on testing, so I ignored this.

The refresh rate was ~60Hz. Victory!

I will now attach the requested 5 * 2 files (for each requested file, one from hardy alpha, and one from hardy alpha + updated intel X driver). Actually, the lspci and ddcprobe outputs are identical as are the xorg.conf files so I will only attach one each of those.

The key difference is in the xrandr logs:
< 1280x768 29.7*+ 60.0
