CPU identification

Hi,
i played a bit with CPUID lately and ran into strange flags/model with my test machine (a Pentium 4 478 box running NetBSD).
Here's the output of my program (first line is found using tables from Linux kernel source).
CPU: Intel Pentium 4 (Foster)
CPU: Brand String: "Intel(R) Pentium(R) 4 CPU 2.40GHz"
CPU: Family 15, Model 4, Stepping 1 (0x0f41)
CPU: Features: 0xbfebfbff
CPU: Features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV
CPU: Features: PAT PSE-36 CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM PBE SSE3
CPU: Features: MONITOR DS-CPL CID xPTR
I've checked Intel docs (P4 specs updates and Xeon specs update), can't find what is my 15/4/1 supposed to be. The Foster codename is nowhere to be found on the net even...
Moreover, i see from CPUID flags it supports HT and SSE3. SSE3 support is surprising for a processor that old. About HT support, motherboard don't seem to think that way, nor my NetBSD kernel (tried both MPBIOS and MPACPI, no SMP found).
Any hints/thoughts/directions?
Cheers,
Mathieu
