If I were arguing for specifying the order in
/sys/arch/i386/conf/GENERIC (etc.), then I would agree. But where the
order needs to be specified is in /sys/dev/isa/files.isa. Since it's
part of the source tree instead of something that would usually be
edited, I think it's OK for the order of items in it to be
significant.
No matter how we do it, I think setting the "probe priority" should be
done when the kernel is configured, instead of after it boots.
