Okay; here's a suggestion for an example hardware name to subarch
mapping:

  EBSA110            -> ?
  Acorn-RiscPC       -> acorn
  FTV/PCI            -> ?
  EBSA285            -> ?
  Rebel-Netwinder    -> netwinder
  Chalice-CATS       -> ?
  unknown-TBOX       -> ?
  co-EBSA285         -> ?
  CL-PS7110          -> ?
  Acorn-Archimedes   -> acorn26
  Acorn-A5000        -> acorn26
  Etoile             -> ?
  LaCie_NAS          -> ?
  CL-PS7500          -> ?
  Shark              -> ?
  SA1110-based       -> ?

The subarch name will be a little more pervasive than just module
aliasing; it'd get used by boot-floppies, keyboard configuration,
kernel-package, and so on.

My proposal is to keep any hardware designed within running RISC OS
in mind of the form `acorn*'; perhaps as people get RISC OS running
on evermore weird and wonderful hardware this will become less useful.

It'd be nice to fill in the `?'s, but it only really pertains to Debian
at the moment, so it's hardly crucial.

If `netwinder' in fact can be more generic, it would be good to know;
no point forcing lots of people to use `netwinder' later on when it's
inaccurate to their platform.

There is, as far as I can tell, no central implementation of a `subarch
name finder'; boot-floppies, anXious, update-modules, kernel-package,
and so on, all do it individually, their own way.  I don't know whether
it's worth trying to go one better than that and provide some sort of
trivial procfs interface for reading subarchitecture names, or have at
least a central stub script to spit the names out, and stick that in
base, or something. <shrug>

Comments appreciated.

(boot-floppies now groks RISC OS disks, for those of you that care.)
