Pardon a possibly stupid question here, but would it not make more sense 
to code the architectures for which these various devices *are* 
possible, rather than requiring each architecture to go through the 
entire config file and add their own "we don't do this" for many entries?

As seen, it is easy for them to be missed, hence all these recent patches.

The way I look at it, it is a lot easier to require that the arch 
maintainer adds specific entries to get their particular hardware 
working, rather than go through a working setup and figure out how much 
they can take away before it breaks.
