O pacote "cpuid" existe no FreeBSD, mas isso não faz parte do sistema básico.
Exemplo de saída:
root@freeBSD > cpuid

Processor serial: 0001-06E5-0000-0000-0000-0000
Acho que o valor que você está procurando é esse "serial do processador".
Então, um simples cpuid |grep "Processor serial"
faria o truque.
Como você disse, não é possível instalar algo no seu servidor, você ainda pode:
- encontrou um lugar como
/tmp
(se você quiser manter o rastreio / lixo baixo), -
obtenha o pacote pré-compilado:
fetch ftp://ftp.freebsd.org/pub/FreeBSD/ports/amd64/packages/misc/cpuid-3.3_6.tbz
(ajuste o URL com o arco do seu servidor - veja
uname -a
para mais informações) -
extraia o binário "cpuid" dele:
tar -jxvf cpuid-3.3_6.tbz bin/cpuid'
-
e executá-lo localmente:
./bin/cpuid
