With the wscons drivers it's possible to hard-wire the definitions into the
kernel configuration, but if it's indeterminte then that's not too useful.

Does this reversal ever happen "on the fly" - e.g. while you're typing into
an xterm? Either way it should be easy enough to solve; ACCESS.bus devices
are supposed to be able to identify themselves, somewhat like SCSI devices -
so it's just a case of adding and testing the code to do that. I'll look at
this soon.
