I don't know. My personal experience was of being first an alien with residence that kept getting extended, and then finally learning Finnish, passing an obligatory language test, and finally acquiring citizenship signed by the then President himself - Mauno Koivisto.

Some investigation is needed to find out what has happened between 1982 and today.

Don't know about permanent residents, but all told approximately 130,000 non-Finnish citizens live in Finland. You're only a Finnish citizen at birth if at least one of your parents is a Finnish citizen. To become a Finnish citizen, you have to have been a resident for at least six years and be able to communicate in either Finnish or Swedish.
