I didn't say "useful".  But at least "booting" e.g. to print out a 
kernel oops because no root filesystem is available or the like should 
be a minimum.  Having the wrong platform configured in might prevent 
even that from working, but at least we shouldn't allow for a kernel 
config that we know in advance has no chance of ever executing anywhere.
