I have a G3 upgraded 8500. The CPU runs at 375 MHz, where /proc/cpuinfo
says 195 MHz, which I think no publicly released G3 ever ran at. In Mac
OS, various utilities tell me 375 MHz, and performance under Linux is at
or around that speed. Another indicator is the "Bogomips" value - which
for the PowerPC CPUs is about 2 x the clock speed. My /proc/cpuinfo says
it's 748, which is a little less the 2 x 375, so yours _SHOULD_ say 1600
or thereabouts ...
