Here's one big difference with the instructions on that page. Since
you built a full kernel rather than building the drm kernel modules
against your current kernel, they're already loaded when boot with the
new kernel. You don't need to unload/reload the drm modules.

That is the i915 version in the 2.6.28 kernel, but the version and
date haven't changed more recently, anyway. To get more current kernel
modules, you can try one of the 2.6.29-rc releases. To get all the
latest intel fixes, though, it's best to use Eric Anholt's drm-intel
kernel.

For the keyboard/mouse issues, you'd probably have to attach an
Xorg.log. Did you build the evdev input driver against the new
xserver?
