We have two projects that I thought were written up somewhere but maybe
not :)

1. Composite by default.

This fixes up open source drivers and infrastructure to allow composited
desktops to be enabled by default, especially with 3D apps and movie
playing. Its mostly catching the open source DRI infrastructure up with
the needs of the modern desktop. It will mostly be targeting Intel
hardware in the initial release.

2. Smooth GUI booting.

The aim is to get from grub to gdm login with only one mode set and make
it all transition smoothly between applications... Again initially
targeted at Intel hardware, we want to move to kernel side device
drivers for graphics cards which should allows up only set the mode once
on boot in an optimal configuration and avoid nasty flickering and stuff
as the machine starts.

Jumping to an Xorg 1.5 pre-release means we also need to deal with a new
pci layer and input hotplug layers.
