I wasn't aware of this difference, but apparently mrg's sparc is
using a dual 100 and a 150 module, which run at different bus
speeds and cache sizes. It may just be that I have a bum module
(or a heat issue?) Perhaps one day I'll pull the box from my
friend's rack and see how the 150 fairs on its own.
