Yeah.  PS had MIPS, then PowerPC (Cell), and currently AMD
(interestingly they also run a modified FreeBSD kernel, but you can't
really get at it...).  Sega Dreamcast had SH4.

I added one more: Tru64 (but I didn't bother to list Digital UNIX or
OSF/1, not sure if software historians consider those different OSes
or just rebrands...).  Patches to improve this little paragraph
welcome.  Pushed.
