incorrect to you, please let me know ASAP.

Driver-Specific Requirements
   -intel:              All Intel chipsets >= i915
          DRI:          DRI2
          KMS:          "On" for all chipsets by default

   -ati:                All Radeon chipsets
          DRI:          3D on chipsets besides Radeon HD 6950
          KMS:          "On" for all chipsets

   -fglrx:              Radeon chipsets R600 and newer only
          DRI:          Unspecified
          KMS:          No

   -nouveau:            All Nvidia chipsets >= NV04
          DRI:          3D on chipsets NV04 and newer *NEW*
          KMS:          "On" for all chipsets

   -nvidia (legacy):    Older Nvidia chipsets
          KMS:          No

   -nvidia (current):   Newer Nvidia chipsets
          KMS:          No

Notable Changes
1.  The default graphical fallback will change from GNOME classic to
    Unity 2D where driver support for 3D is insufficient.
2.  The default display manager will change from GDM to LightDM.
3.  The ubuntu-x team will be maintaining a staging PPA with 
    xserver 1.11 and other components for Ubuntu 12.04, which will be
    available later this year.
4.  For fglrx and nvidia we are exploring post-release driver updates
    for users on an opt-in basis (via Jockey "Hardware Drivers")
