This is something I all ready send to the i386 mailing list.

Problem is netbsd cpuid isn't reporting correctly. I've got a Mobile PII processor (Compaq Armada M300 notebook) facts are the hardware says it as well as other OS's (Windows, Linux) also 
I try with an oficial tool to identify the CPU, from intel for Windows and it also says it's mobile Pentium II. 

One of the develepors in the mailing list said through the fact that the cpuid identifies it as a model 6 (done with an userland tool) it says it's a Celeron. But searching on the Internet I see there are model 6 wich are PII. I don't know if this is really important, don't know if maybe cause the cpuid is wrong it doesn't use all features of the 

I also atach the output done with an userland tool from
