To add even more variables into the mix, this particular machine seems to be running Celeron processor based on P4 core. The case has "Celeron Inside" sticker and althought I haven't opened the case I tend to believe what the sticker tells, because port/misc/cpuid agrees. The local PC assembly company is well known and trusted also. Kernel identifies the CPU as P4, no surprise because CPU core is P4 based. dmesg: Copyright (c) 1992-2002 The FreeBSD Project.
