Well, that might be a usable model for embedded environments, but
since you wouldn't offer PCCARD support, PnP support, or any of
the other dynamic technologies which need high-level intelligence
support, you wouldn't really be much better off than by using a
shell script, so I don't think what you describe will be a much
wanted solution...

And please, could we try to aim the discussion at how we handle the
advanced technologies in or out of devd ?  The degraded cases are 
always easier to handle afterwards.
