Ok
 I popped the 040/33 into the centris and it did not seem to notice the
difference. Apple System profiler still reports the machine as being a
centris 650 with a 25 mhz 040. Just for gigles I \zapped the pram which
seemed to make no difference. It still boots into bsd without a problem.
Where in BSD can I get it to tell me the cpu's megahertz? Dmesg doesnot
seem to mention it....
