DNSSEC does NOT require a lot if CPU. Added DNSSEC validation is
quite possible to all these devices. Some of them already do more
expensive crypto than DNSSEC requires.
I've also run a validating recursive server on my laptops for years
since well before the root was signed. The hardest thing to deal
with is the stupid "transparent" DNS caching servers. They are not
"transparent". They do not deal with non recursive queries. They
do not deal with TSIG or SIG(0).
