[PATCH] Native DMI parser and cross checking with dmidecode

[Sean Nelson]

The DMI Parser is based on dmidecode 2.10's dmidecode.c
Stripped to bare minimums and only parses the System, Baseboard, and 
Chassis tables.
Uses our physmap calls for hardware access.
All of the cross-check code is contained in '#if 1' to easily find and 
shut off usage.
Added my copyright line.
