x86 needs sc, as does sparc64. powerpc doesn't use it by default, but some old
powermac notebooks do not work with vt yet for reasons unknonw. Even so, I've
removed it from powerpc LINT. It's not in daily use there, and the intent is to
100% switch to vt now that it works for that platform to limit support burden.
All the other architectures omit some or all of the screen savers from their
lint config. Move them to the x86 NOTES files and remove the exclusions. This
reduces slightly the number of savers sparc64 compiles, but since they are in
GENERIC, the overage is adequate and if someone reaelly wants to sort them out
in sparc64 they can sweat the details and the testing.
