Ain't that the truth!

Good points.  I picked these up (though with as little reordering as
possible, to avoid introducing new subtle bugs).

Makes sense.  I see you alread submitted this fix to Marcelo.  I picked
it up, too.

Now these I really don't like.  I don't think it's good to clutter
platform-independent config files with platform-specific info just
because xconfig is broken.  As far as I know, these things work
perfectly fine with "oldconfig", "config", and "menuconfig".  (I don't
feel as strongly about this for DEVFS as I do for HP_SIM; but clearly
HP_SIM is such a special case that I'd prefer to keep it in the
ia64-specific config file.)
