Yes, it's a Pentium. While the family ID of Pentium (including Pentium
with MMX) is 5 (that's why it's called 586-class), that of Pentium Pro,
II, III, and Celeron is 6 (686-class). And AFAIK, the initial clock
frequency of Pentium II was 266Mhz when it was introduced.

No, it's not possible. NetBSD gets information from the result of 
cpuid instruction provided by processor itself.
