1. This patch adds CAR for Intel P6 series processors.

2. Add support for Micro-FCBGA 479 Celeron and PIII's
3. Add support for model_6bx and microcode updates
4. Add support for CAR and Tinybootblock on RCA RM4100 and Thomson
   IP1000

Build and boot tested.

Signed-off-by: Joseph Smith <joe@settoplinux.org>

The change to CAR reveiled a few more warnings in the ICH4 and i830 code,
I fixed them on the fly. 

Checking this in because my last two commits broke Joseph's CAR patch. This
version fixes the issues.
