   And on the other hand there is some hardware that just will not work :)
   I know for a fact that a FSBE card will not work in a Sun IPC but runs
   happily in an IPX - something to do with changes to the sbus which
   caused _some_ cards to not work in older machines.


there are also sbus hardware compatibilities with old cards and
newer hardware as well.  eg, from sparc/cgsix(4):

     The double-width `GX' and the `GX+' cards are not compatible with Ultra-
     SPARC machines.
