I know next to nothing about i386 CPUs, but I have this machine:

cpu0 at mainbus0: apid 3 (boot processor)
cpu0: Intel Pentium III (686-class), 1000.09 MHz, id 0x686
cpu0: features 387fbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR>
cpu0: features 387fbff<PGE,MCA,CMOV,PAT,PSE36,PN,MMX>
cpu0: features 387fbff<FXSR,SSE>
cpu0: I-cache 16 KB 32B/line 4-way, D-cache 16 KB 32B/line 4-way
cpu0: L2 cache 256 KB 32B/line 8-way
cpu0: ITLB 32 4 KB entries 4-way, 2 4 MB entries fully associative
cpu0: DTLB 64 4 KB entries 4-way, 8 4 MB entries 4-way
cpu0: serial number 0000-0686-0003-6711-458e-a9ef
cpu0: calibrating local timer
cpu0: apic clock running at 133 MHz
cpu0: 8 page colors
cpu1 at mainbus0: apid 0 (application processor)
cpu1: starting
cpu1: Intel Pentium III (686-class), 1000.04 MHz, id 0x686
cpu1: features 387fbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR>

cpu1: serial number 0000-0686-0002-fc1f-c5a0-64d9

... and it works just fine with NetBSD and a MP kernel.
