This is not Gentoo specific but I found this in a search that is just
getting started:

http://rlworkman.net/howtos/libata-switchover

So, it did happen when switching from old IDE based drivers to the
newer, some claim improved, PATA/SATA drivers.  It appears the kernel
started this but still searching for confirmation.

Like Bill, when it was changed, I just updated the device information in
my programs and went on.  It was the new way and it seemed it was going
to be around for a good long while.  It looks like people who have
created scripts are going to have to fire up vi or nano and do a little
updating. 

Going to search some more to get a better source.
