What does this guy mean by software controlled? Does Jaguar read the model string and set the FSB accordingly at startup?

Almost 100% likely to be OpenFirmware.
This has been true on PowerBooks for some time, actually: OF controls bus and processor speed. So it might be possible for a brave soul to get a 167MHz bus on their dual-867 without breaking out the ol' soldering iron.
They'd probably still void their warranty, though. You can seriously destroy your Mac by entering the wrong thing into OpenFirmware, so this is not a project for the faint of heart.

Do you have a link to PowerBook OFW overclocking?
I've personally destroyed a 7220/200 (4400/200 in the US of A) in OFW trying to install NetBSD. But I think OFW is less dangerous to the solder-skills challanged than changing resistors.
For servers, SPECweb99 <a href="http://www.spec.org/osg/web99/" target="_blank">http://www.spec.org/osg/web99/</a> is a good benchmark because it has lots of disk and network I/O and it keeps the CPU busy as well. Too bad the hardware sites don't seem to know how to run industry-standard benchmarks.

Time will tell.
