>Description:
	When computer boots, following CPU model information is displayed:
pu0 at mainbus0: apid 0 (boot processor)
cpu0: Intel Pentium Pro, II or III (686-class), 1866.73 MHz, id 0x6f6
cpu0: unknown Core FSB_FREQ value 0 (0x41c80000)
cpu0: features bfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR>
cpu0: features bfebfbff<PGE,MCA,CMOV,PAT,PSE36,CFLUSH,DS,ACPI,MMX>
cpu0: features bfebfbff<FXSR,SSE,SSE2,SS,HTT,TM,SBF>
cpu0: features2 e3bd<SSE3,MONITOR,DS-CPL,VMX,EST,TM2,xTPR>
cpu0: "Intel(R) Core(TM)2 CPU          6300  @ 1.86GHz"
cpu0: I-cache 32 KB 64B/line 8-way, D-cache 32 KB 64B/line 8-way
cpu0: L2 cache 2 MB 64B/line 8-way
cpu0: using thermal monitor 1
est_init: unknown system bus clock

	Notice the messages about unknown FSB/system bus clock.

	Though it doesn't seem to actually have any adverse effect,
	it's still better if it would be detected properly.
	
>How-To-Repeat:
	Boot up with this particular Core 2 Duo CPU model
>Fix:
	According to:
	http://www.intel.com/products/processor_number/chart/core2duo.htm

	the FSB value for this particular model is 667 Mhz, which
	means the p3_get_bus_clock() case for Core (model 0xe, 0xf)
	in identcpu.c should perhaps have a this:

                case 0:
                        bus_clock = 6666;
                        break;

	however, I have no idea if the above is correct, so I leave that
	to someone more familiar with the code in question.
