SPORTS PEOPLE; Dispute in Finland

A high Finnish official said she would try to stop Keke Rosberg, a former Formula One champion, from using a Finnish license in competing in the South African Grand Prix at Kyalami next month, but Finnish racing officials said the effort would not keep Rosberg out of the race. ''I want to make sure the Finnish national anthem may not be played in a country which supports apartheid,'' said Kaarina Suonio, the Finnish Minister of Education, who oversees state financial aid to Finnish sports. Antti Syvaelahti, the association's secretary-general, said there was no way the association could keep a professional driver such as Rosberg from honoring his contractual commitments.
