As Jason suggested a sys/arch/acorn would be a good idea; they all look
alike and can share stuff. But technically they aren't all acorns though
:) is the Imago a really new port or a variant on the Acorn theme?

That would bring it down to :
  arch/arm          <- for common code
  arch/acorn        <- for RiscPC, A310/A410,A5000, A7000, RC7500, ....
  arch/hpcarm ?     <- iPAQ, eval boards and other hand held devices?
  arch/armisapci    <- for ARM boards using only std. PC pheriphals using
                       ISA/PCI like CATS, EBSA, DNARD, ....

but what about a Corel Netstation (or who owns it now?) where to classify
it then? Maybe a arch/arm32 could be a good idea to cover all the
arch/armisapci (lame name i admit) and other devices.

That I must admit too...
