This looks awesome Keith! Great Work :-)
I can only see one thing that needs fixing and it is cosmetic:

Lines 394-395 of bootlog look good:

CPU: vendor Intel device 673
CPU: family 06, model 07, stepping 03

But, Line 411 of bootlog:  CPU: .

+	/* Print processor name */
+	fill_processor_name(processor_name);
+	printk(BIOS_INFO, "CPU: %s.\n", processor_name);

Is the %s not working?
