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.
