Actually, the concept of hostid remained present.  4.4BSD changed
the preferred access mechanism from a syscall to a sysctl.  FreeBSD
has o{g,s}ethostid under COMPAT_43 and kern.hostid.

Note that the 4.4BSD, Lite1, Lite2 and final include code to extract
the hostid out of a SPARC ID prom.  I don't know if this is still
relevant to UltraSPARC machines.
