Thank you Gregory, I've been reading between the lines, and this is
pretty much what I expected you to say.  So in the past when
OEMs/systems manufacturers have been irresponsible/inept like this we
have implemented flags to force ignore the values coming out of the
bios.  As it's now obvious that the problem here is a legal/regulatory
issue, I'd hope that having a force flag would be acceptable from a
that perspective.  I'm no lawyer, but I expect once a user decides to
explicitly set a force flag to ignore the bios values I'd suspect the
responsibility would shift from the manufacturers and back onto the
user.

Would such a patch be theoretically acceptable?  If so I'll write up a
patch to do this and submit it next week hopefully.
