Interesting. OBP has created a 'clock-divisors' property for the processor node. At this point the only reason that I can imagine that your system might not support cpupm is if the CPU driver either does not exist or failed to attach. Check to see that the driver exists: /platform/sun4u/kernel/drv/sparcv9/us If not, then it appears that SUNWus has not been installed? Try 'pkginfo SUNWus' to verify. If it does exist, then check your /etc/driver_aliases file and make sure that there is an entry: us SUNW,UltraSPARC-IIIi If so, check /var/adm/messages for any messages coming from the 'us' driver.
