Your method does not work on any of the Suns that I have tried it on.  In
the case of one of our SPARCstation 5 Suns, "hostid" returns 80770895. 
The low 24 bits of that is hex 770895, which is decimal 7800981.  However,
the Serial Number printed on the back of the CPU box is 532F0945.

In the second example (another SPARCstation 5),"hostid" returns 807709d8. 
The low 24 bits of that is hex 7709d8, which is decimal 7801304.  However,
the Serial Number printed on the back of the CPU box is 532F09B1.

In the third example (an ULTRA 1),"hostid" returns 8080a9d5.  The low 24
bits of that is hex 80a9d5, which is decimal 8432085.  However, the Serial
Number printed on the back of the CPU box is 639F1F29.

In the fourth example (a SPARCstation LX),"hostid" returns 8031dc0f.  The
low 24 bits of that is hex 31dc0f, which is decimal 3267599.  However, the
Serial Number printed on the back of the CPU box is 350E1234.

In the fifth example (another SPARCstation LX),"hostid" returns 8031aae6. 
The low 24 bits of that is hex 31aae6, which is decimal 3255014.  However,
the Serial Number printed on the back of the CPU box is 35031258.
