Huh. Wonder what the rationale was behind this, unless the cpuid detection
isn't really necessary for newer kernels to work on an older CPU. After all,
one of the strengths of Linux is that it runs, and runs well, on 386 and 486
boxes. Makes putting up a cheap firewall, DHCP/DNS/print server, or router
a snap.
